UV Plots

Although images are a wonderful way to display results, problems may be more obvious in UV plots of visibilities as a function of UV radius or time. GO UVALL will make these plots. This macro is controlled by 3 basic parameters: the UV Table name (NAME), the type of data to be plotted along the X and Y axis (XTYPE and YTYPE). These two variables can take the following values:
U and V       Fourier coordinates
ANGLE         UV position angle (Atan(V/U))
RADIUS        UV distance (Sqrt(U^2+V^2)
TIME          UT Time of visibility (in hours)
DATE          Date of visibility (in days)
NUMBER        Visibility number
REAL          Real part of the visibility
IMAG          Imaginary part of the visibility
AMP           Amplitude of the visibility
PHASE         Phase of the visibility
WEIGHT        Relative weight of the visibility
SIGMA         RMS noise on REAL and IMAG
First and last channels can also be specified.
