K2flix: Kepler pixel data visualizer
K2flix makes it easy to inspect the CCD pixel data obtained by NASA's Kepler space telescope. The need for this tool arises from the fact that the two-wheeled extended Kepler mission, K2, is affected by new sources of noise -- including pointing jitter and foreground asteroids -- which are more easy to spot by eye than by algorithm. The code takes Kepler's Target Pixel Files (TPF) as input and turns them into contrast-stretched animated gifs or MPEG-4 movies. K2flix can be used both as a command-line tool or using its Python API.
