XPARM
Type: Adverb   (Real(10))
Use:  A general adverb which contains ten elements as parameters to some
      process.  When used with YPARM  XPARM refers to the X-coordinate.
      It is used almost exclusively for the parameters of the gridding
      convolution function specified by XTYPE.
Null value:   Usually 0.
      See help files UVnTYPE for n = 1 to 6.
Procedures:
   CXPOLN........Procedure to make complex polarization images and beam.
   LINIMAGE......Build image cube from multi-IF data set.
Tasks:
   ACFIT.........Determine antenna gains from autocorrelations.  XPARM
                 is misused to list Rpol Tsys(IF).
   BSGEO.........Beam-switched Az-El image to RA-Dec image translation.
   BSGRD.........Task to image beam-switched single-dish data.
   CONFI.........Optimize array configuration by minimum side lobes.
                 XPARM  provides selection parameters for the mask image.
   CONPL.........Plots AIPS gridding convolution functions.
   HOLGR.........Read & process holography visibility data to telescope
                 images.  XPARM provides correcgtion and threshold
                 parameters.
   IMAGR.........Wide-field and/or wide-frequency Cleaning / imaging task.
   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.
   UVIMG.........Grid UV data into an "image".
   UVMAP.........Makes images from calibrated UV data.
