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, Pillow, matplotlib and pandas.
Quick start
Let's get the positions of the sun between two times:
from sdss import Region
ra = 179.689293428354
dec = -0.454379056007667
img = Region(ra, dec)
To see the image:
img.show()
To see the image in three gri filter bands (green, red, infrared) separately:
img.show3b()
To find 10 nearest objects in a radius of 5 arc degrees:
df_obj = img.nearest_objects(radius=5, n=10)
To find 10 nearest objects with spectrum in a darius of 5 arc degrees:
df_sp = img.nearest_spects(radius=5, n=10)
