NOISE N1 N2 N3 NCOPY METHOD [READ PHOT] SEED -- Copies a series of spectra,
NCOPY times, adds noise.
Parameters:
N1 -- Slot number of first spectrum to copy
N2 -- Slot number of last spectrum to copy
N3 -- First slot for copies
NCOPY -- Number of copies.
METHOD-- 'E' -- Adds noise according to error bars on spectrum. The
error bars on the output spectra are identical.
'M' -- Adds noise by assuming a certain number of photons/mJy.
Takes no account of error bars on spectrum.
If METHOD.EQ.'M' you need to specify:
PHOT -- Number of photons/mJy
READ -- Read out noise in photons to act as a floor.
In any case:
SEED -- Seed integer for random number generator
Enter 0 to carry on from old value.
