Are there source lists that combine photometry from multiple filters?
Multi-wavelength source lists, combining photometry from multiple filters, are now available. Whenever data in more than one filter are available for a given visit, sources are identified in the white light image, but the photometry is carried out separately in each filter, generating separate source lists for each filter. However, sources corresponding to the same area/location of the image are given the same ID number, thus users can in principle unambiguously cross-match sources across filters. For convenience, starting with DR5 users can obtain directly a combined source list that provides matched photometry for each source across filters. These lists are associated with the Level 2 Total images and with the Level 4 (color) images in the same way as the regular source lists are associated with Level 2 data products for each filter, and are accessible from the DAOCat and SEXCat columns in the Inventory view, as well as from the “More associated files” button in the Images view.
