Code / Software
LSDCat
LSDCat is a conceptually simple but robust and efficient detection package for emission lines in wide-field integral-field spectroscopic datacubes. The detection algorithm is based on a 3D matched-filtering approach for emission line objects. The software also measures fluxes and extents of detected lines. LSDCat is implemented in Python, with a focus on fast processing of large data-volumes.
kendall.py
kendall.py
contains a function for calculating the generalised non-parametric
correlation coefficient (Kendall's τ). The generalised Kendall's τ measures the
strength of correlation for a paired sample of ordinal level data that is partly
partially censored (either with upper- or lower- limits, but not with mixed upper-
and lower limits). It can also be used as a statistical test to rule out the
null-hypothesis that the two variables are uncorrelated.
