spaxelsleuth

spaxelsleuth is a python package for analysing data from large IFU surveys, such as SAMI, on a spaxel-by-spaxel basis.

spaxelsleuth takes as input data cubes and other data products, e.g. emission line fits and stellar kinematics measurements, and outputs a pandas DataFrame where each row represents a spatial pixel (spaxel) in a galaxy, and the columns represent various measurements. In addition to storing data products from large surveys in an easy-to-use format, spaxelsleuth computes extra quantities, such as extinctions, emission line ratios, and metallicities, so you don't have to! spaxelsleuth also comes with a set of useful plotting and data visualisation tools to help you analyse your data.

spaxelsleuth was originally developed to work with data from the Sydney-AAO Multi-object Integral field spectrograph (SAMI) survey but contains extensions to work with fitting output from LZIFU and S7, and can be adapted to ingest data from other surveys.
