NAME

marks - puts labels on tv images

SYNOPSIS

marks [filename] [help] [echo] [row=] [col=] [num=]

DESCRIPTION

This routine takes in ASCII data from stdin or optional filename as a table in the format similar to that generated by stars or phot .

index row col

Where the numerical index is ignored and is assumed to have white space in front of it. Lines without whitespace such as headers are ignored. The program then plots the row and column positions and displays them as crosshairs on any Xwindow tv image. The actual columns can be over-ridden by command line switches.

If the num= number is specified the star number found in this column is displayed at the row/col locations.

EXAMPLE

To show the stars labels found from the stars command, use:

stars crab | marks

BUGS

The convention of ignoring lines without leading white space characters can cause confusion.
