The following files contain XYPLAN files of spiral galaxies.

The extension indicates the number of arms in the spiral.

Each map has been designed to have relatively sparse arms, with
a dense galactic core. It is the intent to assign one homeworld
per arm. With this in mind, the top stars in each galaxy are placed
midway out the arms.

Example
~~~~~~~

There is a 9-armed spiral galaxy in XYPLAN.009; the 9 top stars are
500, 499, 498, 497, 496, 495, 494, 493, 492.  Each of these is placed
on it's own spiral arm.

These spirals were generated in 1/2 hour using VPGALAXY, the 
Galaxy Former!  Uploaded by author of same, cjsmith@io.org.
