New version of the Archive Science Portal

Archive Science Group 2 years ago in Layout, Appearance and color scheme updated 2 years ago 1

Dear users,
we are happy to announce that a new version of the Archive Science Portal has been released and announced to the scientific community here

Based on user feedback a new view mode has been implemented as a central new feature in addition to the already existing sky view (left-hand panel of figure above). It allows users to inspect, at a glance, the multi-dimensional query space in up to seventeen 1D distributions (right-hand panel of figure). They include physical parameters like sensitivity and signal-to-noise ratio, alongside more traditional ones such as Programme ID or instrumental setup. Users can easily interact with any list or histogram to add or remove search constraints and to build up rather complex queries in a progressive fashion.  

Beyond that, the updated Archive Science Portal provides the following improvements:

  • the capability of bookmarking and sharing queries;
  • customizable set of query parameters and management of query constraints;
  • improved layout and support for mobile and touch devices;
  • several bug fixes.

New version of the Archive Science Portal -> V2.0

Archive Science Group 2 months ago in Layout, Appearance and color scheme updated 2 months ago 1

Dear users,

we are excited to announce that ESO Archive Science Portal has been substantially upgraded. The full list of improvement present in the new version 2.0 has been announced to the scientific community here.



Following users feedback, the updated Archive Science Portal provides (among others) the following improvements:

  • A single interface allows users to access data from La Silla Paranal, APEX ,and -now- from ALMA as well:
    Whale Galaxy
    See for instance here the ALMA footprint over the WHALE galaxy.
    These ALMA data can be retrieved also with this programmatic query:
    SELECT
    s_ra, s_dec, dp_id, instrument_name, obstech, proposal_id, obs_release_date
    FROM
    ivoa.ObsCore
    WHERE
    intersects(s_region, circle('',3.72333,-39.19667,0.3))=1 AND instrument_name='ALMA'


  • We now provide previews for datacubes, including interactive spectrum extraction:
    Muse Spectrum
    Users can now extract a quick look MUSE spectrum directly from the Archive Interface

  • Search within user defined polygons:
    Jewel Box
    For instance an user can download all the spectra of the stars in the Jewel Box cluster within a customized region. Naturally this is possible also programmatically:
    SELECT
    s_ra, s_dec, dp_id, instrument_name, obstech, proposal_id, obs_release_date
    FROM
    ivoa.ObsCore
    WHERE
    intersects(s_region, POLYGON( 'J2000', 193.15859,-60.21354,
    193.40507, -60.15885,
    193.80660, -60.21094,
    193.85447, -60.38943,
    193.61956, -60.49661,
    193.21774, -60.49711,
    193.00831, -60.43487,
    193.04188, -60.33450,
    193.03932, -60.26952) )=1 AND obstech NOT LIKE 'IMAGE%'

Exploring the Follow up of GW events

Archive Science Group 2 months ago in Search for data updated 2 months ago 1


We would like to stress the power of the new version of the archive science portal for detecting electromagnetic counterpart of gravitational wave detections. For instance, you can easily search for all data present in the archive associated to the irregular 50% confidence contours for the location of the GW superevent s191205ah: Polygon-1, Polygon-2, and Polygon-3.

    The procedure followed to obtain the results above is described in our Jupyter notebook. Where you can also find some useful tools to explore the archive science portal and to unleash the full power of the programmatic access. You can find more notebooks here.

    Search for targets with target name

    Anonymous 5 months ago in Search for data updated by Archive Science Group 5 months ago 1

    it is not much clear how to search for a target. I tried to look for Sedna spectra, I tried typing Sedna, SEDNA, 90377 Sedna, 90377 SEDNA, and all the possible combinations on upper case, lower case, numbers, with spaces, without spaces, ecc, but I can't get any result. What am i doing wrong? I wasn't neither able to find an instruction page.


    Thanks

    Archive Science Group 5 months ago

    Dear anonymous user,

    thanks for your message and for using the Forum :)


    The problem seems to be that there are no reduced products available for Sedna. In fact, also the search for coordinates (03:52:37 +07:58:18) produces no result.

    There are a few FORS2/ISAAC observations of SEDNA in the raw data query form (pull-down menu selection in the green area=> "search by OBJECT FITS keyword", or input "sedna" in the "title" field of the pink area)

    Finally, there are also external services like the "Solar System Object Image Search" at CADC that is scanning, among many others, some of the ESO image data collections (*) and returning lists of datasets containing potential observations of the SSOs. This service even provides links to the ESO archive for data download. I found 302 matching images (WFI, EFOSC, ISAAC, FORS).

    I hope this helps, but please do not hesitate to write us if you still have doubts or problems.

    Cheers,

    Chiara (on behalf of ASG)


    PS In the Archive Portal, if you put your mouse arrow on the target window, a small facet with instructions will appear automatically and explain what kind of input is accepted and in which format.

    The 'create a link to this page' functionality

    Dear Archive Science Portal users,

    thanks to an anonymous user, we just discovered that there is a small bug with the 'create a link to this page' button. 

    In fact, when one uses this functionality to create a link to a search around given coordinates (with any other constraints),
    the link erroneously points to null coordinates instead. 

    We are already working to solve this. Meanwhile, a smart and quick way around that allows one to get back the right query via the generated link is to click on the red, curved arrow below the coordinate windows and on the right side of the FoV (see attached screenshot).

    After clicking, you will see that your research will point to the right coordinates (and have all the other constraints).


    Many thanks to the anonymous user who spotted this bug.

    We are looking into the problem already and will report here any updates.


    Cheers,

    ASG

    New feature of the ESO Archive Science Portal: searching by list of targets

    The possibility of searching by a user-provided list of targets has been added to the Archive Science Portal
    In the first implementation of this feature the list may contain up to 1000 target names or coordinates (J2000 or galactic). The power of the existing graphical user interface remains fully available in the list search mode, including the option of adding and adjusting any of the seventeen non-positional search parameters. 

    The new software release also features a refurbished download menu to accommodate downloading the results of the list search and it includes several bug fixes.
    As usual, we would love to hear from you! So, please provide here your feedback on the usefulness of the current implementation, or suggest new features or simply ask us questions on how to use ASP!

    Cheers,

    ASG

    Trouble accessing all images from IMAGE(pawprint)

    tknapp 2 years ago in Search for data updated by Archive Science Group 2 years ago 1

    I'm attempting to download a dataset of 16 images, when I download the file I'm only given one image. This is the object information:

    Object

    00:43:58.64

    RA (J2000)

    -73:12:17.85

    DEC (J2000)

    303.68

    Galactic longitude

    -43.91254

    Galactic latitude

    0.6 deg²

    Sky Coverage

    1.65°

    Field of View

    0.594"

    Sky Resolution

    Data

    IMAGE (PAWPRINT)

    Data Type

    21.115

    Sensitivity (AB mag at 5σ)

    Unfortunately, the object that I am interested in is not contained in the one image I am able to download. Can someone give me a hint as to how I can access all the images from this dataset? 

    Thanks!

    Answer
    Archive Science Group 2 years ago

    Thank you for your question tknapp!

    The image that you are downloading is a multi-extension file (MEF), with each detector images stored as 16 FITS extensions in the image file. If you are displaying such FITS file with DS9 you only see extension #1 by default. You can display all the 16 extensions by choosing this option in ds9. Alternatively, you can display each extension using the commandline ``ds9 filename[n]'' with n = 1-16.

    A useful short guide on the data format of the science data products is available here:

    PI filter

    Reinhard Hanuschik 2 years ago in Search for data updated by Archive Science Group 2 years ago 1

    When using the P.I. filter, users are probably not aware of the fact that multi-OB data logically can have more than one P.I. On the archive science portal such data have no P.I. (field is empty). With a P.I. filter set to a specific name, such data are NOT visible (although the selected P.I. contributed at least partially to the data).

    It would probably be good to modify the underlying logics such that data are always shown if the specified P.I. has contributed (either in the traditional sense, one OB has one run has one P.I.; or in the advanced way, the data product has contributions from one P.I.).
