DESCRIPTION

UVSECTOR flags visibility data with a specific sector. The sector can be specified either by position angle, or as an hour angle (East-West array assumed) or by way of a stripe direction in an image. The latter form will be useful when a stripe is seen in an image (implying bad visibility data), and you wish to flag out the visibility data that could have produced this stripe.  

PARAMETERS

vis
The visibility file to flag. Several files can be given. Wildcard expansion is supported. The default is no file.
select
Extra selection criteria. In addition to being in the appropriate sector, the data must satisfy the selection criteria before it is flagged.
angle
This defines the angle of the axis of the sector, if the sector is given by a position angle or hour angle (for an EW array). It consists of two values, the first being either the string "uvangle" or "hangle" (for position angle and hour angle, respectively). The second gives the angle in degrees or hours (for position angle and hour angle respectively). Position angle is defined as degrees clockwise from the v axis (which is consistent with the uvplt definition).
in
If the sectors position angle is given by a stripe direction, this gives the name of the image to associate with the stripe.
region
A long, thin, region of the image given above, running in the direction of a stripe. This parameter must be given if you are defining an hour angle by a stripe direction. Normally you will generate this region using CGCURS's region option, and generate a region along the ridge of a stripe.
width
The full width of the sector, in degrees. This must be in the range (0,180). The default is 5 degrees.
options
Extra processing options. Several can be given, separated by commas. Minimum match is used. There is currently only one option.

             flags.
