KEPLER_AZIMUT

          KEPLER_0  in  the computation (Azimut Zero corresponds to the oriented
    minor axis, i.e. is at KEPLER_ROTA in the sky plane).

    For example 90 270 indicates Az between 90 and 270 degrees, while 270 90 in-
    dicates As from 0 to 90 and 270 to 360.

    The Azimut coverage can be visualized using command SHOW KEPLER_VELO.
