I tried reading your report instead. I've privately sent you more detailed
comments, but the bottom line is I can't read your results without a
hand calculator and ephemeris. The RA and dec in the observation
reports require a factor of 36 and a bunch of zeros; the Julian date
of 6 and several digits is off by some other factor (Jan 0 1999 is 2450813.5
for reference, these obs are probably not a year old). I simply cannot
thoughtfully consider your findings without some clue as to date and time.
I know this is a casual demonstration of the database, but I am
not encouraged by it, to say the least. This kind of stuff - cryptic
results from large databases - bugs me personally, so I won't say
more publically otherwise. I can say I'm glad to see that a "test database",
something I've advocated for some time, is apparently around in
some form. Hope it is online for the rest of us.
