NAME

mkphottb -- Create a synthetic photometry lookup table for WF/PC

USAGE

mkphottb infile outtable

DESCRIPTION

This task creates an STSDAS table which contains the synthetic photometry quantities to be used in the WF/PC pipeline calibration software, the calwfp task.

PARAMETERS

infile = "" [string]

Name of the input text file. This file contains the photometry modes and must have the following syntax: camera,detector,data mode,unit,filter name 1, filter name 2,flatfield

Each mode should take one line and if either of the filter slots is not used, the word OPEN should be in its place. There is no limit on the number of lines in the input file.

outtable = "" [string]

Name of the output table. The output table has the following columns:

PHOTMODE	Photometric mode. (ch*30)
PHOTFLAM	Inverse sensitivity. (real)
PHOTZPT		Photometry zero point in magnitude. (real)
PHOTPLAM	Pivot wavelength in Angstrom. (real)
PHOTBW		RMS bandwidth of the filter used in Angstrom. 
		(real)
CAMERA		Camera in use. (ch*2)
DETECTOR	Detector ID. (int)
FILTNAM1	Name of the first filter. (ch*6)
FILTNAM2	Name of the second filter. (ch*6)
FLATFIELD	Flat field calibration flag. (ch*3)

graphtab = "crcomp$hstgraph_*.tab" [string]

Names of the synthetic photometry graph tables.

comptab = "crcomp$hstcomp_*.tab" [string]

Names of the synthetic photometry component tables.

EXAMPLES

1. Create a synthetic photometry lookup table phot.tab, using an input text file test.lis.

w_> mkphottb test.lis phot.tab

where test.lis is a text file containing the following lines:

wf,1,a,dn,f439w,open,cal
wf,2,a,dn,f439w,open
wf,3,a,dn,f439w,open
wf,4,a,dn,f439w,open
pc,5,a,dn,f702w,open
pc,6,a,dn,f702w,open
pc,7,a,dn,f702w,open
pc,8,a,dn,f702w,open

REFERENCE

BUGS

If the input string contains items not been parsed by the synthetic photometry routines, it will issue a harmless message, e. g.

Input keyword a not used in graph search
Input keyword open not used in graph search
