Specifications for CALMON in 2MAPPS v3.0:

1) CALMON will utilize the photometric intervals for each night defined 
   during preliminary processing and quality assurance review.  Only 
   calibration scans determined previously to be in photometric intervals
   will be included in the final processing.  There will be no attempt
   to recover additional photometric intervals for any night.

   The cal scans to be used for final processing, and the previously
   defined photometric intervals will be supplied as input parameters
   to CALMON.

2) CALMON will have the ability to fit, plot and report coefficients and
   RMS residuals for a linear fit zero point offset (in J) and a constant 
   zero point offset in H and K<sub>s</sub>.  Fits are to be weighted
   by the inverse of the airmass of the individual scans.  The
   J-band linear fit will be permitted for 3 or more calibration scans.

3) CALMON will also have the ability to fit, plot and report coefficients and
   RMS residuals for a polynomial of order 2 for the zero point offset 
   in J-band.  The polynomial fit is to be weighted by the inverse of the 
   airmass of the individual scans.  The J-band polynomial fit will be 
   permitted for 5 or more calibration scans.

4) For photometric intervals where both linear and polynomial J-band fits are
   applicable, CALMON will default to the fit that results in the lower
   chi-squared statistic, where the chi-squared is evaluated using
   the uncertainties and weights associated with each calibration scan.

5) CALMON will have the ability to apply "breaks" in previously defined
   photometric intervals.  The location of these breaks are to be
   specified via a namelist parameter, and are presumed to be a result of
   quality assurance review "overrides" to the default calibration procedure.
   During the newly defined intervals, more than one new continguous 
   photometric interval can be defined, subject to the definitions
   and fits defined above.  The specification of contiguous intervals
   means that a calibration set may be the endpoint for one or two
   photometric intervals.
