     4  Use of options.photcode:
     5    - M_REFLIST: used to assign a photcode value to the loaded data
     6    - M_REFCAT: used to select data from the reference of the given photcode
     7    - M_FAKEIMAGE: used to assign a photcode value to the generated data
     8    - M_RESORT: unused
     9    - M_IMAGE: is used to override or supply the image header photcode
     10               * only valid for single chip runs

     12  Re: MOSAIC_PHU
     13      - the mosaic phu needs to have the time to enable the image/mosaic match
     14
     15      - NX,NY are used for plotting the mosaic outline.  the center of
     16        the mosaic is 0,0, and the mosaic outline is drawn from
     17        -NX/2,-NY/2 to NX/2,NY/2.  A problem: NX,NY in Image is using
     18        a short int.  If the units of the FPA/TPA coords are microns, this overflows.
     19        * change NX,NY to int?
     20        * require the use of mm not microns?
     21        * for GPC, NX,NY ~ 384000 um excluding gaps
     22
     23      - only the astrometry, time, and NX,NY are loaded for MOSAIC_PHU headers.

     27  I am working on adding the ability to read MEF files containing
     28  multiple tables and multiple image headers.  Here are the details:
     29
     30  SIMPLE CMP:
     31    PHU:
     32      NAXIS = 2 or
     33      SIMPLE = FALSE or
     34      TEXTMODE = TRUE (use option; global variable)
     35
     36  SIMPLE CMF:
     37    PHU:
     38      NAXIS = 0
     39      NAXIS1 exists, > 0
     40      NAXIS2 exists, > 0
     41    EXT:
     42      EXTNAME = SMPDATA, PS1DATA, etc (defines layout)
     43
     44  SIMPLE MEF:
     45    PHU:
     46      NAXIS = 0
     47      NAXIS1 does not exist
     48      NAXIS2 does not exist
     49      &CTYPE[4] is not "-DIS"
     50      EXTEND is true
     51    EXT HEAD:
     52      EXTTYPE = IMAGE
     53      EXTNAME = image.name
     54      EXTDATA = table.name
     55    EXT DATA:
     56      EXTTYPE = SMPDATA, PS1DATA, etc (defines layout)
     57      EXTNAME = table.name
     58      EXTHEAD = image.name
     59
     60  MOSAIC MEF:
     61    PHU:
     62      NAXIS = 0
     63      NAXIS1 does not exist
     64      NAXIS2 does not exist
     65      &CTYPE[4] is "-DIS"
     66      EXTEND is true
     67    EXT HEAD:
     68      EXTTYPE = IMAGE
     69      EXTNAME = image.name
     70      EXTDATA = table.name
     71    EXT DATA:
     72      EXTTYPE = SMPDATA, PS1DATA, etc (defines layout)
     73      EXTNAME = table.name
     74      EXTHEAD = image.name
     75
     76  MOSAIC PHU:
     77    PHU:
     78      NAXIS = 0
     79      NAXIS1 does not exist
     80      NAXIS2 does not exist
     81      &CTYPE[4] is "-DIS"
     82      NEXTEND = 0 or 
     83      EXTEND is false
     84
