Hi there:

Yes, the boxes for W and E of Greenwich are apparently  'merged' a little,
though the times for the Greenwich meridian and Lat 52 degs seem the same
whether E or W is specified   However, times of transit of the sun on 28th
August 2003 at Greenwich and at Lat 52 degs are given as 13:01:21 but
WinEphem gives it as 13:03. I am not sure which is correct.  (For ref:
times for East (given as 07:32:36) are 07:34:10 on WinEphem and times for
West (given as 18:30:37) are 18:31:51 on WinEphem.

I suspect in the case of the East/west figures that refraction (which is
approximated in WinEphem) might not be being considered in your package -
though I suspect that one needs to take it into account at such extremes.
However if so, why does the time of transit differ by one and a half mins? 

Patrick
