IN4DISK
Type: Adverb  (Real)
Use:  Disk unit # associated with the input image
      given by IN4NAME, IN4CLASS, IN4SEQ.
Null value:  0
      Null value usually means search all disk units.
Verbs:
   CLR4NAME....Clears adverbs specifying the fourth input image
   GET4NAME....Fills 4th input image name parameters by catalog slot
               number.
   IM4HEAD.....Displays the image 4 header contents to terminal, message
               file.
   M4CAT.......Displays images in the user's catalog directory for
               IN4DISK.
   Q4HEADER....Verb to summarize the image 4 header: positions at
               center.
   U4CAT.......List a user's UV and scratch files on disk IN4DISK.
Tasks:
   COMB........Combines two images by a variety of mathematical
               methods.  The 4th image is of noise for the 2nd image.
   GREYS.......Plots images as contours over multi-level grey.  The
               4th image is for color blue.
   IMAGR.......Wide-field and/or wide-frequency Cleaning / imaging
               task.  The 4th image is of spectral curvature.
   KNTR........Make a contour/grey plot file from an image w multiple
               panels.  The 4th image is of polarization angle or U.
   MEDI........Combines four images by a variety of mathematical
               methods.
   OOSUB.......Subtracts/divides a model from/into a uv data base.
               The 4th image is of spectral curvature.
   PCNTR.......Generate plot file with contours plus polarization
               vectors.  The 4th image may be used for contours or grey
               scale.
   PDPLT.......Plots selected contents of PD tables.
   RMFIT.......Fits 1-dimensional polarization spectrum to Q/U cube.
               The 4th image is from FARS, either the phase or the
               imaginary part.
   TVSPC.......Display images and spectra from a cube interactively.
               The 4th image is an optional XYf cube to be displayed one
               f at a time.
   VBGLU.......Glues together data from multiple passes thru the VLBA
               correlator.
   WTSUM.......Task to do a a sum of images weighted by other images.
               The 4th image is of weights assigned to the 2nd image.
Procedures:

               The 4th image is of spectral curvature.
   IMSCAL......Large image self-cal with IM2CC and OOCAL.
               The 4th image is of spectral curvature.
   LINIMAGE....Build image cube from multi-IF data set.
               The 4th image is of spectral curvature.
   OOCAL.......Determines antenna complex gain with frequency-dependent
               models.  The 4th image is of spectral curvature.
   OOFRING.....Fringe fit data to determine calibration with spectral
               index options.  The 4th image is of spectral curvature.
