Notes:

- All the science images (UBVRIzK) are PSF matched to a common 
  Moffat profile with FWHM of 1.2" and 1.3" for 1030 and 1256 
  respectively.

- K-band images are flux calibrated using common stars in the 
  2MASS survey.

- Optical images are flux calibrated using Landolt standards
  as described in Gawiser et. al 2006.

- K-band images are reprojected to the BVR image projection 
  (Gawiser et al. 2006). 

- Pixel scale: 1 pix = 0.267"

- The rms maps (*_rms.fits) pixel values correspond to the 
  background flux rms in an aperture of 1.4*FWHM diameter at the 
  pixel coordinates.

- The mask files (*_bpm.fits) correspond to the mask used 
  to reject regions arround bright stars and noisy edges before 
  detection.

- The weight files (*_weight.fits) are the normalized 
  inverse square of the rms maps. Equivalent to a normalized 
  exposure map. 

- The detection images (*_det.fits) used to create 
  the K-selected catalogs, correspond to the psf matched images 
  divided by the normalized rms map and masked using the mask 
  files.
