PYMORPH: automated galaxy structural parameter estimation using PYTHON
Abstract
We present a new software pipeline - PYMORPH- for automated estimation of structural parameters of galaxies. Both parametric fits through a two-dimensional bulge disc decomposition and structural parameter measurements like concentration, asymmetry etc. are supported. The pipeline is designed to be easy to use yet flexible; individual software modules can be replaced with ease. A find-and-fit mode is available so that all galaxies in an image can be measured with a simple command. A parallel version of the PYMORPH pipeline runs on computer clusters and a virtual observatory compatible web enabled interface is under development.
