SADD N1 N2 N3 HJD0 PERIOD METHOD AC AS -- Adds or multiplies a set of
spectra by a sinusoid of fixed period at every wavelength.
Useful for computing window function with SDEC
NB. This routine has to access the arrays in the wrong direction and may
therefore page fault alot.
Parameters:
N1 -- Slot number of first spectrum to process
N2 -- Slot number of last spectrum to process
N3 -- Slot of first output spectrum
HJD0 -- HJD0 of sinusoid
PERIOD - Period of sinusoid
METHOD - 'A' -- Add to data according to D = D + sinusoid
'M' -- Multiply data. D = D*(1.+sinusoid)
'R' -- Replace data. D = sinusoid
AC -- Amplitude of cosine component
AS -- Amplitude of sine component.
Sinuosoid computed as AC*COS(2*PI*PHI)+AS*SIN(2*PI*PHI)
where PHI = (HJD-HJD0)/PERIOD
This command belongs to the classes: time series and binary .
