WRPHOT
Name
wrphot
Purpose (one Line)
Write a standard raw photometry data file (Pluto format).
Description
This creates a .001 format Pluto-Charon format file from the input
photometry. As a suggestion, use .000 as a suffix if these are NOT
standard magnitudes (such as differential to some star), and use
.001 if they are magnitudes on a standard system.
