In contrast with the original version, after installation (see below) you now import the flipper module you need from the flipper package. For example,
from flipper import liteMap
import flipper.fftTools as ft
Flipper is a light-weight python tool for working with CMB data which broadly provides three main functionalities: A suite of tools for operations performed on maps, like application of filters, taking gradients etc. An FFT and power spectrum tool, implementing the core concepts from Das, Hajian and Spergel (2008) http://arxiv.org/abs/0809.1092v1
Plus, Flipper has awesome visualization tools based on Matplotlib.
Flipper has become one of the most heavily used base codes in the Atacama Cosmology Telescope collaboration and led to a slew of papers with over 300 citations.

- Fork and clone this repository
- In the repository root directory, run
pip install -e . --user
That's it! Now you should be able to import flipper modules as described earlier from anywhere on your system as long as pip is installed correctly.
The -e makes symbolic links instead of copying files, so don't delete the cloned repository after. Changes you make will be reflected immediately. You are encouraged to make useful changes and issue pull requests to help maintain this code.
