ROTATE
Type:  Adverb (Real)
Use:  ROTATE is a general adverb used to denote rotation.  The units are
      degrees.  Generally the sense of rotation is such that a positive
      rotation will cause the image to  rotate counter-clockwise.
Null Value:  NONE  (0 is 0)

Verbs:
   COODEFIN......Define or modify an image axis coordinate description.
Procedures:
   LINIMAGE......Build image cube from multi-IF data set.
Tasks:
   BSGRD.........Task to image beam-switched single-dish data.
   BSROT.........Modifies SD beam-switch continuum data for error in
                 throw.
   FIXBX.........Converts a BOXFILE to another for input to IMAGR.
                 ROTATE is the new facet rotation.
   FLATN.........Re-grid multiple fields into one image incl sensitivity.
   IMAGR.........Wide-field and/or wide-frequency Cleaning / imaging task.
   KNTR..........Make a contour/grey plot file from an image w multiple
                 panels.  ROTATE is applied to the polarization vectors
                 when plotted.
   OOSRT.........Sort a UV dataset into a specified order.
   PCNTR.........Generate plot file with contours plus polarization
                 vectors.  ROTATE is applied to the polarization vectors
                 when plotted.
   PROFL.........Generates plot file for a profile display.  ROTATE
                 rotates the plotted X-Y plane.
   SCIMG.........Full-featured imaging plus self-calibration loop with
                 editing.
   SCMAP.........Imaging plus self-calibration loop with editing.
   SDGRD.........Task to select and image random-position single-dish
                 data.
   SDIMG.........Task to select and image random-position single-dish
                 data.
   UVPLT.........Plots data from a UV data base in multiple ways.
                 ROTATE is used only when one axis is along a UV
                 position angle.
   UVSRT.........Sort a UV dataset into a specified order.
   VLABP.........VLA antenna beam polarization correction for snapshot
                 images.  ROTATE is the parallactic angle.
   WIPER.........Plots and edits data from a UV data base using the TV.
                 ROTATE is used only when one axis is along a UV
                 position angle.
   XYMOD.........Compute linear polarization point source model, applies
                 to data.  ROTATE is the rotation measure in radians per
                 meter squared,
