Automated Scanning

class llabs.auto. AutoScan ( ** kwargs ) [source]

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.
