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.
My cats
Below are the two cats, Spaxel and Voxel, that choose me as their human after my arival at IUCAA in November 2023.
