Auto scanning algorithm
Methods Summary
__init__
(**kwargs)llfind
(resolution, data, npix1a, npix1b, ...)Looping over spectrum to find lyman limit and corresponding Lyman-alpha.
findsatreg
(data[, limshift, dvtrans, ...])Look for Lyman alpha signature of DLA type systems by looking for wide velocity absorption.
getbestz
(allsys, data, **kwargs)For all HI transitions available in the spectrum, measure the velocity dispersion, and re-estimate the redshift in the closest redshift range available.
getparam
(data)Determine the column density and Doppler parameter of the DLA by locate precisely the wings of the Lyman alpha.
