An anonymous ftp site is now available containing about
300 IDL routines which may be of general interest.
These routines have not been tested for PV-WAVE.
The routines are available as compressed tar files for unix,
and compressed backup files for VMS (a decompress utility for
VMS is also available from this site).
The routines mostly fall into the following broad categories:
Text Files, Text strings, Date & time routines, Information,
Plotting/Graphics, Imaging, Array processing, Math routines,
Programming routine, Miscellanious, FITS image routines.
Many of the routines should work on any computer system, some
require X windows, some require Postscript printers. Many have
been run on VAX VMS, SUNOS, HP-UX, and MSDOS.

timeaxis = Plot a time axis.
ymd2jd = From Year, Month, and Day compute Julian Day number.
set_isoxy = Set data window with equal x & y scales.
psinit = Redirect plots and images to postscript printer.
makez = Make simulated 2-d data. Useful for software development.
imgunder = Display image in same area as last plot.
