    I've analysed this and your other 7 observations of 92-23A, along with
    17 others by three experienced UK observersand they are excellent!  Only
    one shows a mistake in position.
    
    Here the the residuals, showing the corrections needed in RA(in min) and
    Dec(in '), and the cross-track error(in ') and along-track error (in
    sec).

    As I say, only one big mistake, which is pretty good going.  Keep up the
    good work!
