    Yes, Peter, you understood the principle correctly. Except that the unit (=
    resolution of the azimuth table) is 0.1deg, not 0.1' as you say. The sun needs
    24s to move 0.1deg in LHA. The change in azimuth in the course of a whole day is
    on average the same. But it will usually be faster at noon and can be
    considerably slower (even zero) at other times.
