ISIS basic radial velocity measurement tool question
Posted: Tue Aug 08, 2017 12:27 pm
Hi all,
I'm curious to know - when using the basic radial velocity measurement tool in ISIS (ie, converting the profile to velocity centred on a particular wavelength and then using the FWHM tool via mouse) - Is the value calculated by ISIS based on flux weighting, peak position or some combination?
Thanks,
Paul
