If blank, compute image

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.
