Trouble accessing all images from IMAGE(pawprint)
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:

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
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.
