Appendix IV
Calculating the major azimuth standstill values for 2007
Below ten major azimuth standstill closest to the major azimuth
standstill
limit are determine in 2007 for Callanish. The data is gotten
from JPL,
no correction has been done on these numbers (so the azimuths are
slightly off due to varying altitude). Remember that these 2007 dates
and not so extreme as in 2006!
The bold row is the date which is the most extreme azimuth
standstill
limit in 2007 for that location (using JPL).
The below columns mean:
Date and time [UTC], C(ivil)/N(autical)/A(stronomical)twilight/*=sun
above horizon, r(ise)/s(et), azimuth, apparent altitude, moon phase
(full=100%).
