IPython magic for importing science

It's like %pylab but with less littering of your namespace.

git clone [email protected]:ucsc-astro/science_magic.git
cd science_magic
pip install .

with the last line prepended by sudo for most python installations.

You can make the new line magic commands automatically load as an IPython extension by adding the following to your ipython_config.py (usually located at $HOME/.ipython/profile_default):

c.InteractiveShellApp.extensions = ['science_magic']

Otherwise, you can load the extension manually with the magic command %load_ext science_magic.

%science does the following imports

import numpy as np
import pandas as pd
from astropy.coordinates import SkyCoord
from astropy.table import Table
from astropy.io import fits
from astropy import units as u
from astropy import constants as c
import matplotlib as mpl
import matplotlib.pyplot as plt
import seaborn as sns

In addition, it sets up a default plotting enviroment with the following matplotlib.rcParams settings:

savefig.bbox = tight
figure.figsize = (9, 6)
text.usetex = True
image.origin = lower
image.interpolation = none

and the following seaborn settings:

context = poster
style = ticks
font_scale = 1.0
color_codes = True
palette = deep

%astro will just do the astropy imports, and %plotting will just do the matplotlib and seaborn imports.

You can pass a dictionary of rcParams settings as the line argument of either %plotting or %science (e.g., %science {'errorbar.capsize': 2} to update the default plotting settings.

Want to use this structure to set your own imports? Don't like my default plotting settings? Just edit the relevant files under the science_magic/science_magic directory. E.g., to add an import for astropy.time.Time, just add from astropy.time import Time to science_magic/science_magic/astro_imports.py.
