IN = NDF (Read)
The input NDF containing the data to which noise needs to be
added.
NOISE = LITERAL (Read)
The noise type to introduce into the data. Either Gaussian or
Poissonian, which may be abbreviated to G and P. [P]
ADU = REAL (Read)
The scaling factor to
convert the data values in the input NDF to counts for which Poisson statistics are assumed valid. [1.0]
SIGMA = REAL (Read)
The standard deviation of the gaussian noise. [1.0]
OUT = NDF (Write)
The output NDF to contain the data with noise added.
