ASTRdata
MakeNoise is part of GNU Astronomy Utilities 0.19. 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

- $ info gnuastro
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
