This package makes it easier to find, download, and manipulate cosmological data products for plotting purposes.
This package is not registered so cannot be downloaded using a package manager. However, you can install using
git clone git@github.com:gplynch619/cosmo_data_tools.git
cd cosmo_data_tools
pip install .
Data products from major cosmological experiments, such as Planck, SPT, etc., are available online but in disparate locations and formats. This makes it inconvenient to compile these data for plotting purposes and creates an overhead for making simple plots comparing data to model predictions. cosmo_data_tools streamlines this process by downloading these data upon request and converting to a consistent format across datasets. For example, to compare the Planck 2018 and SPT-3G TT powerspectra, you can simply run
import matplotlib.pyplot as plt
from cosmo_data_tools.cmb.planck_2018_TTTEEE import planck_2018_TT
from cosmo_data_tools.cmb.spt3g_2018_TTTEEE import spt3g_2018_TT
planck = planck_2018_TT()
spt = spt3g_2018_TT()
fig,ax=plt.subplots()
ax.errorbar(planck.ell(), planck.Dl(), yerr=planck.Dl_err())
ax.errorbar(spt.ell(), spt.Dl(), yerr=spt.Dl_err())
plt.show()The first time cosmo_data_tools is asked to plot a specific data set, it will download it from official sources and store for later use. There is more functionality as well detailed in examples.ipynb.
