    Thanks Ted for correcting my obs.
    Using your references I was able to conclue I indeed used the wrong stars to
    reduce my obs.
    From my notes the sats passed through a triangle of stars I id-ed as 15 and
    18 UMA and
    a star at 09:14:00 +54:17:02; but the real stars of that triangle were 18
    and 17 UMA and a
    star located at 09:29:48 +55:44:43, a mag 6.5 star. Ted used CG UMA which is
    to
    close to 17 UMA to fit my sketch of the star triangle.
    
    For the second point of my 03- 54 A obs I get a slightly different reducing:
    28095 03 054A   4252 F 20040330201601170 17 25 0915707+564448 37 S+050 05
    
    For the second point of 03- 53 C I get:
    28097 03 054C   4252 F 20040330201608540 17 25 0927060+555713 78 S+050 05
