Chapter 2: Skymap Subclasses

In this chapter we introduce the subclasses of cartosky.Skymap and explore some of their features for astronomical plotting.

# Basic notebook imports
%matplotlib inline

import matplotlib
import pylab as plt
import numpy as np
import healpy as hp

We start by importing several classes from cartosky and setting a few constants that we will use in this example.

# Import skymap and some of it's basic map classes
import cartosky

from cartosky import Skymap,McBrydeSkymap,OrthoSkymap
from cartosky import SurveySkymap,SurveyMcBryde,SurveyOrtho
from cartosky import DESSkymap

SKYMAPS = [Skymap,McBrydeSkymap,OrthoSkymap]
SURVEYS = [SurveySkymap,SurveyMcBryde,SurveyOrtho]
ZOOMS   = [DESSkymap]

In the last tutorial we saw how we could create skymaps with different projections using the projection keyword argument to the Skymap initializer. However, for ease of use we have also defined a set of subclasses for commonly used projections.

fig,axes = plt.subplots(1,3,figsize=(20,4))
for i,cls in enumerate(SKYMAPS):
    plt.sca(axes[i])
    smap = cls()
    plt.title(cls.__name__)
