astromorphlib

Overview

Python scripts to analyze the morphology of isolated and interacting galaxies. The package is designed to download S-PLUS (https://splus.cloud/), Legacy (https://www.legacysurvey.org) and SDSS (https://www.sdss4.org/dr17/imaging) images automatically. There are functions to calculate a 2D sky background of the images and deblended segmentation maps of interacting systems with merger isophotes. The non-parametric analysis is performed by using statmorph package (https://github.com/vrodgom/statmorph).
The user can study the environment of the object/system by downloading a list of the galaxies within Field-of-View of S-PLUS/Legacy images from SIMBAD server (http://simbad.u-strasbg.fr/simbad/). In addition, there is a function to display DSS2 (http://alasky.u-strasbg.fr/hips-image-services/hips2fits) images of any size.
