MakeProfiles - make standard 2D profiles on an image


astmkprof [OPTION...] [Options] [Catalog]


MakeProfiles is part of GNU Astronomy Utilities 0.14. MakeProfiles will create a FITS image containing any number of mock astronomical profiles based on an input catalog. All the profiles will be built from the center outwards. First by Monte Carlo integration, then using the central pixel position. The tolerance level specifies when the switch will occur.

For more information, please run any of the following commands. In particular the second contains a very comprehensive explanation of MakeProfiles's invocation: expected input(s), output(s), and a full description of all the options.

All options and their values:
$ astmkprof -P
Inputs/Outputs and options:
$ info astmkprof
Full section in manual/book:
$ info MakeProfiles

If you couldn't find your answer in the manual, you can get direct help from experienced Gnuastro users and developers. For more information, please run:

$ info help-gnuastro

Magnitude is for peak pixel, not full profile.
mcol is total brightness, not magnitude.
Mode of '--ccol': 'img' or 'wcs'.
-p, --tunitinp

Sersic index or Moffat beta.
Second Euler angle (X-Z-X order).
Third Euler angle (X-Z-X order).
Position angle (First X-Z-X Euler angle in 3D).
Axis ratio (major/dim3 in 3D).
Axis ratio (major/dim2 in 3D).
Effective radius or FWHM in pixels.
Truncation in units of --rcol, unless --tunitinp.
WCS parameters:
