Description:

The data are 4554 light curves derived from images taken of the globular cluster M4 by the Kepler space telescope during the K2 portion of its mission, specifically during Campaign 2 of that mission, which occurred in 2014. A total of 3856 images were taken over approximately three months at a cadence of approximately half an hour. The purpose of these observations was to find stars and other objects that vary in brightness over time --- variable stars. Also included is a table with associated information for each of the 4554 objects and their light curves. Please consult README.txt for file information. In brief, object_information.txt is a table containing information on the 4554 objects for which we obtained light curves, and wallace_data.tgz is a zipped tarball containing a copy of README.txt, object_information.txt, and the 4554 individual light curve files (*_lc.csv). LICENSE.txt contains the license under which the data are released.
