HELP SECTION

MFIMG
Task:  One of three operations related to TECOR:
       (1) Make image of magnetic field model (Bx, By, Bz, F) in
           Gauss
       (2) Print both magnetic field models every 10 degrees in
           nano Teslas
       (3) Make images of TEC
Adverbs:
  IMSIZE.....Desired image size in cells.  The TEC cube ignores
             this and sets IMSIZE = 73,71.
  CELLSIZE...Desired cell spacing, currently assumes sec.  The
             TEC cube ignores this and sets CELLS = 5, 2.5 degrees
             or 5, 5 degrees for AIT.
  OUTNAME....Output image name (name).     Standard behavior
             with default = 'MagField img'.
  OUTCLASS...Output image name (class).    Standard defaults.
  OUTSEQ.....Output image name (seq. #).   0 => highest unique.
  OUTDISK....Disk drive # of output image. 0 => highest number
             with sufficient space.
  OPCODE.....Image projection type: ' ' rectangular,
                'AIT' Aitoff, 'MER' Mercator
  OPTYPE.....Model of field: ' ' old MAGDIP routine,
                'IGRF' new IGRF version 13 code
  OUTPRINT...If not ' ', print comma separated list of values to
             text file.  Values are every 10 degrees and the
             other adverbs are ignored.
  INFILE.....IONEX file.  If not ' ' and OUTPRINT = ' ', make image
             of the IONEX file,  OPCODE is used as are OUTNAME, et al.
  NPOINTS....The output TEC cube is created before the data are read.
             Set NPOINTS > 49 if the data has a map every quarter hour,
             set NPOINTS > 25 if the data has a map every half hour,
             NPOINTS > 25 if there is map every hour,  else 13 is
             used for data every 2 hours.  CODG types have data
             every hour, JPLG types have data every 2 hours.  CASG
             has data every half hour.  UQRG has data every quarter
             hour.
