Basic Information on imstore
Task: imstore
Purpose: Write out image data in an ascii format.
Categories: map analysis
IMSTORE is a Miriad task which dumps or tabulates a region of
an image in a format suitable for other programs.
Different output modes can be selected.
Key: in
The input file name. No default.
Key: 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.
Key: clip
Only image pixels above the clip value are written. The default
is all data.
Key: scale
Scale factor with which the image data is multiplied
before output. The default is 1. Note this scaling is done before
the clip test (as described above).
Key: mode
Output mode. This determines the format of the output. Currently
accepted are: dump, uvgen and nemo. The default is dump.
mode=dump writes out the values of the selected pixel, only, with
there being 8 pixels per line.
mode=uvgen produces an output suitable for input to uvgen.
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.
mode=nemo outputs in the format:
DRA, DDEC, FLUX
Key: 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)''
Key: units
Units of the output axes. Valid options are "absolute" and
"relative" (with respect to the reference pixel).
If an axis is a known astronomical coordinate system, the units
are displayed in arcsecs. The default is "relative".
Key: log
The output log file. The default is the terminal.
