A high level routine that uses various scriptsto assemble a cdfp file from mido (Measure IDentified Objects) data for an image.

% midophot2cdfp --help    

 

Here is a sample calculation with a real acm image.

Image = 20180206T022042.6_acm_sci_proc.fits
X,Y     =   518.1  625.7
Ra,Dec  =   1:33:40.515 +30:19:14.05
Mag30   = 15.719 

midophot2cdfp tells me: 
ZPSEC              = -3.06280
EXPTIME            = 5
EXPTIME correction = 1.747425    (expC) 

Usingthe PS2 webtool I find: 
g,r,i = 13.990 13.631 13.503 

From my cdfp_panstarrs.sh tool:
     RA_hrs        DEC_deg        g         r         i         B         V         R                                                     
   1.561267614  30.320371628    13.990    13.631    13.503    14.385    13.758    13.468

To get this B:        B = Mag30 + ZSPEC + expC  =  15.719 - 3.063 + 1.747  =  14.403
                                                        B from PanSATRRS   =  14.385       delm = 0.018
