Hello there!
The routine that you are describing doesn't seem to be a very common
one, so I am not sure how many people have used it or even heard of it
(I haven't). Check the routine's source code - most likely a file named
partvelvec.pro for the header. The header (if any) should contain
information about how the routine is meant to be used, what it does,
what parameters it accepts, etc. If you didn't find what you are looking
for in the routine's header, you should contact either the person who
gave you the routine or the routine's author (author's name and contact
SHOULD be in the routine's source code, double check!)
Hope that was of some help,
