DESCRIPTION

IMTAB is a Miriad task which tabulates selected regions of an image in a format suitable for programs like UVGEN. Different output modes can be selected:

The UVGEN format outputs, in (8f10.4) format:

    FLUX,DRA,DDEC,WMAJ,WMIN,WPA,POLN,POLPA
where the last 5 parameters are set to 0.0. DRA and DDEC are given in arcsec w.r.t. the reference pixel if the axis type is a recognized astronomical one.

The NEMO format outputs, in (3g16.9) format:

    DRA, DDEC, FLUX

See also IMSTORE and IMLIST for simular functionality.

in
The input file name. No default.
region
The region of interest of the input. Default is the entire input. Full region specifations are supported. Note: 3D datacubes do not display their 3rd coordinate.
clip
Only tabulate scaled (see SCALE=) image data above the clip value. Default: all data.
scale
Scale factor with which the image data is multiplied before output and clip test (see CLIP=). Default: 1.0.
mode
Output mode. Currently accepted are: uvgen, nemo. Default: nemo.
format
Override the default mode-dependant output format. Default: none. Note: The format specification must be a legal fortran format, including the parenthesis; e.g. ``format=(3F20.10)''
