FAST: Fourier analysis of spectroscopic timeseries
A typical sequence for reading and setting up data, setting up a template,
cross-correlating and analysing the resultant velocity shifts, total absorption
light curve and might look as follows.
; read in and prepare the 2d spectra for analysis
fitsdata / brucedata
; compute cross-correlations, clean velocity curve and analyse
; analyse equivalent width variations
; analyse light curve
The procedures are all interconnected and entirely experimental, so
you will have to figure out why it breaks and fix it for yourself.
readxy, writexy, resample, qqsm, rxr, ryr, sp2rd, sp2wr, vcorr, xcorr
Positions and relative strengths of atomic lines are marked against a plot showing
stellar spectrum and (if present) a theoretical model.
