[vsnet-chat 3893] RZ Leo astrometry

[Gianluca Masi <gianmasi@fr.flashnet.it>]

Dear Colleagues,
I've found that SIMBAD gives the following (J2000.0) position for RZ Leo:

R.A.: 11 37 16.17 Decl.:+01 49 20.8

For this star I've found, measuring one of my images [vsnet-alert 5453] ,

R.A.: 11 37 22.27 Decl.:+01 48 58.9 (J2000.0)

There is quite a big difference... I can comment only my astrometry, saying it is
reasonable, with 0.2" residuals. My position is based on 10 reference stars from USNO
A2.0.

DELTA(RA)~6s; DELTA(Decl)=21.9", that is the two "points" are about 1.4' apart.

Regards,
Gianluca
