How do I coadd my new GI observations to preexisting GALEX data to improve S/N (Special Coadds)?
From cycle 5 onwards proposers may request special co-added data sets, made using the GALEX pipeline software. Special co-adds may be requested for any data that will be released in GR-6, although the maximum exposure time that can be guaranteed is that currently available in GR-4/5 (as listed in TOAST). Special co-adds will be treated the same way as new observations – they will be proprietary to the proposer for 6 months after the proposer is notified of their availability in MAST, and will become public after that. Special co-adds will not become part of the regular GRs, but will continue to remain available as (publicly released) GI data at MAST. New+archival co-adds will become available to the GI’s on the same schedule as the new observations. Special co-adds will have all the same data products as standard co-adds, and will be contained in standard (3840 x 3840 pixels, 1.6 x 1.6 degree) GALEX image.
