# If you want to remove differential extinction across each frame,
#   place values for the first-order extinction coefficients here.
#   Typical values are B 0.40, V 0.20, R 0.10, I 0.08
#   You must specify a filter,value pair for each filter, like so:
#            fixk  { V 0.20 } { I 0.08 }
#   If you do not wish to correct for differential extinction,
#   use values of 0.0 for all filters
#
fixk     { V 0.20 } { I 0.06 } 
#fixk     { V 0.00 } { I 0.00 } 

# if set to 0, then the photom program will set to BAD_MAG
#              the calibrated mag of any star detected
#              in only a single passband (or ignore it 
#              completely, so it doesn't appear in output).
# if set to 1, then the photom program accepts stars detected
#              in a single passband, applying the photometric
#              solution to them with no color term.
# If you set this to 1, be sure to set the corresponding
#    parameter to 1 in the "collate.param" file, too.
