I received a copy of UCAC2 yesterday from the USNO. The coverage has not been expanded yet. This one is identical to the set sent to the Observatory last...
Dear All, as a "new" user of both UCAC 2 and USNO B1.0 catalogues, I was wondering which is the real importance of the number of calibration stars for the best...
... By simple error propagation, the random error in the alignment of the astrometric reference frame to your image is d/sqrt(n), where d is the random error...
Luca, forget the 5 star matches. Better go with USNO-B1.0 with your 12' x 12' field. With so few stars the distribution on your field will be bad and in the...
... An additional point is that with double the number of stars in USNO-B2.0, you can use a higher order fit and thus beter represent the non- linearities in...
