ESO Archive Frequently Asked Questions
CalSelector: In some cases the association is marked as incomplete, but it seems to me that all the necessary files are there. Could you, please, advise?
In addition to the files strictly needed for processing, the CalSelector attempts to include in the dataset also additional files that can be of general interest (e.g. acquisition images, through slit images, standard stars in different filters than the science to compute photometric color terms, etc.). If these "secondary" associations are incomplete, the whole dataset is marked as incomplete. More information on the missing files is provided in the corresponding "messages" section of the xml file included in each dataset.
