KEPLER_THETA

              Maximum  angle  (in degree) from the disk projected major axis be-
        yond which the spectra are not considered in the averaging process.

        This angle is needed because  the projected rotation velocity is  degen-
        erate  to  zero along the minor axis, which results in a lower effective
        angular resolution in this direction. This effect depends  on  the  disk
        inclination: a larger angle can be used for less inclined disks.

        The  default  is 60 degree.  The Azimut coverage can be visualized using
        command SHOW KEPLER_VELO.
