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.
