The WFCAM Science Archive has the concept of deprecated WFCAM images (see e.g. the description of deprecated column here http://wsa.roe.ac.uk/www/gloss_d.html). However the WFAU module doesn't seem to have the option of only downloading undeprecated images?
Here is my best guess for where the deprecated value might be specified in the code, but the query always returns both deprecated and undeprecated images.

I realize this functionality may be missing from the WFCAM archive itself, as the web-form does not have a deprecated field. Upon submitting the web-form, a table is returned that has the deprecated values for each image, and the user can manually choose to only download undeprecated images. I was wondering if anyone here has any insights on how to do this programatically through astroquery?
