Cygnus-X Survey Photometry mosaics or "tiles"


The mosaics in this directory are the images used by the photvis program
to perform the source detection and photometry for the Cygnus-X survey
catalogs and archives in Data Delivery 1.  The clustergrinder program was 
used on the BCD version 18.5 to create the mosaics from the data.  See the 
data delivery description document for more information.

The data were processed mostly using a single AOR per mosaic tile, except for
a few small AORs that were combined with adjacent AORs.  See the list in the 
table below for a mapping of each AOR to image tile.

The files in this directory have names of the form IX_tileNNNN_mos.fits or
IX_tileNNNN_msk.fits, where X is the IRAC channel number (1, 2, 3, or 4 for
the 3.6, 4.5, 5.8 and 8 micron channels, respectively), NNNN is the 4-digit 
tile label (see table below) and the *mos.fits files being the flux image
and the *msk.fits file is an image that shows the depth of coverage at each 
point. The *msk.fits file shows the overlaps between frames, and also where
pixels have been rejected due to being bad pixels in the arrays, or having 
cosmic rays, saturation, or other effects that could cause a pixel to be 
rejected.
