[ADVANCED\]UV_CIRCLE [x0 y0 Rota Incli]
[/SAMPLING QSTEP [Unit [QMIN QMAX]]] [/ZERO [Flux]]
Compute a UV table containing the radial distribution of the azimutal
average of the visibilities after deprojection for inclination and ori-
entation (Incli, Rota, in Degrees) around a specified center (x0,y0 in
Radians). All arguments default to 0. ROTA is here the position angle
of axis of (assumed) rotational invariance of the object. Thus, when us-
ing results from UV_FIT one should use ROTA = PA-90, where PA is the Po-
sition Angle of the Major axis.
The resulting UV table have visibilities only with V values equal to 0,
so that the U values contain the radial distance in the UV plane. This
is convenient to display the azimutal average of the visibilities as a
function of UV distance, but cannot be used for further imaging.
See UV_RADIAL if you want to image the circular average of the bright-
ness distribution.
