10 major standstill dates around the azimuth standstill limits up to 2100

Below ten major azimuth standstill closest to the major azimuth standstill limit are determine for the period 2006-2100 (for location Callanish I). The data is gotten from JPL, so one has to correct the azimuth's for having the events at the same apparent altitude (using linear interpolation for more details e-mail me). This correction is done in all the below tables (value corrected azimuth is last column).

The bold row is the date which is the real azimuth standstill limit for that location (using JPL and linear interpolation).
The red dates are dates mentioned by Meeus ([1997], table 5A) as major (declination) standstill limits.
The below columns mean:
Date and time [UTC], r(ise)/s(et), azimuth, apparent altitude, moon phase (full=100%), corrected azimuth (not corrected for shape of moon).
