Welcome to SCORPIO’s documentation!¶
SCORPIO (Sky COllector of galaxy Pairs and Image Output) It is an application that generates images of pairs of galaxies, in different surveys and filters.
Is a tool to quick generate images of galaxy pairs, using data from different surveys. To use SCORPIO you need python 3.7 or higher, and have the following libraries:
numpy
astropy
matplotlib
astroquery: The latest version of astroquery can be conda or pip installed: conda install -c astropy astroquery or pip install astroquery
(It is suggested to create a virtual environment if you do not want some of these packages to be permanently hosted in your most used libraries)
This program receives RA and Dec information from a pair of galaxies. interacting (or nearby) or other individual objects and download the data Corresponding .fits of survey data and list of filters:
Survey >>> Filters
Sloan Digital sky Survey (SDSS) >>> [u, g, r, i, z]
Two Micron All Sky Survey (2MASS) >>> [J, H, K]
Wide Field Infrared Survey Explorer (WISE) >>> [3.4, 4.6, 12, 22]
Later it processes and exports an image.
For this it has a series of steps that use some specific purpose functions:
Process >>> Function
Download .fits data >>> download_data
Stack the information >>> stack_pair
Calculate distance to the observer Mpc and the separation between the pair >>> distances
Generate the image >>> Image.plot
