I found a few bugs in the version of "merge" that a I posted.
Result is that tables get populated and files are read but
results are invalid in many cases.
I found one dumb error. There are likely more as this does
not explain all the invalid result.
1) (in catalog.c) I am working in RA and DEC in units of mas
(milliacrseconds) and storing in four byte integers. I am
trying to do math and getting overflows and wrap arounds.
(a^2 + b^2 != c^2 if mas is stored in int4)
I need to convert to 64bit floats for internal computations.
I like finding dumb errors. They are easy to fix.
I've had the flu the last few days and beed unable to
focus on a CRT screen for more then 20min at a time.
Should get this fixed in the next few days.
I am interrrested in bug reports. Nothing gets fixed that is
not first reported.
