Questions
search within image viewer field or around crosshair position?
is it possible to search for data within the current field of view of the image viewer or around the position of the crosshair?
Answer
Thanks for your question Ian!
Regarding the first part: searching the data within the current FoV of the sky view is the default behaviour. As you zoom and pan using the sky view, the results are continuously adjusted according to the current field of view.
Second part: shift+left mouse click triggers a search at the current pointer position (not at the cross hair) with an initial search radius of 1 arcsec (1”). Then, the radius can be adjusted according to your preference using the drop-down menu near the top left. Note: the radius field also allows numeric input.

thank you. the search around the cross-hair works - but the updating of the search as you move the FoV doesn't seem to work for me on either Safari or Firefox (on a mac running 10.12). on both the search window looks as though it is updating the search but returns no data for regions where i know there is imaging data.
Hi Ian,
are you not finding data in a specific region of the sky you are interested in, or the updating of the search as you move the FoV does not work at all, no matter which FoV you start with?
e.g. If you reset everything and you try to zoom-in do the search table and the sky view update and show data?
if i start from scratch and zoom in - then i get the behaviour you claim. however, the problem seems to be if i start by entering a source name or coordinate in the box at the top-left and then try to pan away from that position - it doesn't then seem to update (even if i then clear the content of the search box).
Ah, I see! In this case, panning away is not enough to remove the object selection. You are also right that cleaning the content of the search box does not work in this case. The way to proceed is to click on the small "x" on the blue box specifying the "target" on the top left of the page, on the right side of the "Archive Science Portal". Once you remove the target selection, the FoV will remain the same, but more data will appear both on the sky view and in the result table.
I hope this clarified your doubts, if not, do not esitate to write us again!
