GLIMPSEII v1.0 Image Delivery - May 2007 - 3.1 x 2.4 deg mosaics

  This is SSC version S12.4 processing of the GLIMPSEII data taken in
  September 2005 (epoch 1).

   3.1 deg x 2.4 deg Mosaic images of l= 7.45 to 10.1 deg and l=349.9 to 352.55 deg,
   b= +-1.2 deg of the GLIMPSEII SURVEY region; 1.2" pixels

   Each mosaic fits file is about 270 MBytes. jpeg files are around 600 KBytes per file.
   Each mosaic fits file has an associated .hdr file which contains the fits
   header from the fits file and additional information about the individual
   frames included in the mosaic image.  For example, the associated .hdr file
   for GLM_00900+0000_mosaic_I1.fits is GLM_00900+0000_mosaic_I1.hdr.

  NOTE
  These mosaics were originally delivered in March 2007.
  We are re-delivering these mosaics with a few changes to the fits header (and .hdr file). 
  The images have not been changed, nor have the 3-color jpegs.  In the new fits header we 
  clarified the exposure time information and added a keyword, NEXPOSUR, which gives the
  *typical* number of exposures that went into the mosaic image. For the v1.0 GLIMPSEII 
  data, NEXPOSUR=2.  There are areas where the actual number of exposures is 1 (near the 
  edge of the survey coverage) and greater than 2 (overlaps between AORs) but the number 
  of visits for the vast majority of the September 2005 epoch 1 data is 2.

  New:

  FRAMTIME=                  2.0 / [sec] Time spent integrating each BCD frame
  EXPTIME =                  1.2 / [sec] Effective integration time each BCD frame
  COMMENT DN per pixel=flux(photons/sec/pixel)/gain*EXPTIME
  NEXPOSUR=                    2 / Typical number of exposures
  COMMENT Total integration time for the mosaic = EXPTIME * NEXPOSUR
  COMMENT Total DN per pixel=flux(photons/sec/pixel)/gain*EXPTIME*NEXPOSUR

  ETIMEAVE=               1.2000 / [sec] Average exposure time for the BCD frames

  Previous:

  FRAMTIME=                  2.0 / [sec] Time spent integrating (whole array)
  EXPTIME =                  1.2 / [sec] Effective integration time per pixel
  COMMENT DN per pixel=flux(photons/sec/pixel)/gain*EXPTIME

  ETIMEAVE=               1.2000 / [sec] Average exposure time
