The program
Aperplates.f
the different variations 1,2,3,4,5,6 have different imput format to match
the different .coo files.

Reads inp.coo writes in.coo.

*****************************************************************************
Below a few lines from inp.coo
These files are from Hwankyung Sung and the star positions are given as
relative positions in arcmin from the cluster center.
Line 1 is the coordinate of the centre of the circular aperture, again measured
from the cluster centre.
The program apercenters.f computes the RA and Dec of the apertures from the
relative coordinates of the aperture plate centers.

For each star the program then reads the star name, the V mag and the delta RA
and delta dec (last two columns).
It outputs the x and y coordinates in mm and the information about the stars.

The light is dispersed in the "Y" direction.
Check that stars are not closer than 0.4mm (POINT) or 1.0mm (SLOT)
and edit out those that do.
A few lines are then added to the top (see readme_asc2dxf for details)
to produce input for asc2dxf
