sdss

A python package for retrieving and analysing data from SDSS (Sloan Digital Sky Survey)

Installation

Install the latest version of sdss from PyPI:

pip install sdss

Requirements are numpy, requests, Pillow, matplotlib and pandas.

Quick start

Let's create a Region:

from sdss import Region

ra = 179.689293428354
dec = -0.454379056007667

reg = Region(ra, dec, fov=0.033)

To see the image:

reg.show()

To see the image in three gri filter bands (green, red, infrared) separately:

reg.show3b()

To find nearest objects:

df_obj = reg.nearest_objects()

To find nearest objects with spectrum:

df_sp = reg.nearest_spects()
