Overview
Python scripts to analyze the morphology of isolated and interacting galaxies.
The package is designed to automatically download imaging data from:
- S-PLUS (https://splus.cloud/)
- Legacy Survey (https://www.legacysurvey.org)
- SDSS DR17 Imaging (https://www.sdss4.org/dr17/imaging)
The library also includes functionality to perform photometric modeling using simulated galaxy images, allowing controlled experiments and validation of morphological measurements.
There are functions to:
- Calculate a 2D sky background of the images
- Generate deblended segmentation maps of interacting systems with merger isophotes
- Perform non-parametric morphological analysis using the
statmorphpackage.
Users can also study the environment of an object/system by downloading a list of galaxies within the Field-of-View of S-PLUS/Legacy images from the SIMBAD server (http://simbad.u-strasbg.fr/simbad/).
In addition, the package includes a function to display DSS2 images (http://alasky.u-strasbg.fr/hips-image-services/hips2fits) of any size.
