SYNOPSIS

       astmknoise [OPTION...] ASTRdata

DESCRIPTION

       MakeNoise is part of GNU Astronomy Utilities 0.5.  MakeNoise will add noise to all the pixels in an input
       dataset. The noise parameters can be specified with the options below.

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

       All options and their values:
              $ astmknoise -P

       Inputs/Outputs and options:
              $ info astmknoise

       Full section in manual/book:
              $ info MakeNoise

       Full Gnuastro manual/book:
              $ info gnuastro
