Basic Information on uvsector
Purpose: Flag a sector of UV data.
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.
The visibility file to flag. Several files can be given.
Wildcard expansion is supported. The default is no file.
Extra selection criteria. In addition to being in the appropriate
sector, the data must satisfy the selection criteria before
it is flagged.
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
If the sectors position angle is given by a stripe direction,
this gives the name of the image to associate with the stripe.
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.
The full width of the sector, in degrees. This must be in the
range (0,180). The default is 5 degrees.
Extra processing options. Several can be given, separated by commas.
Minimum match is used. There is currently only one option.
