K2 Campaign Fields
Overview | Field Dates and Positions | Campaign Field Visualizations | Machine-Readable Files
Each K2 Campaign has a duration of approximately 80 days and remains fixed upon a single boresight position. This page details the K2 Campaign fields. See sections 1.2 and 1.3 of the K2 Handbook for details, as well as Data Release Notes for each individual campaign.

Machine-Readable Files
As a convenience for users, machine-readable files in a variety of formats are provided here. The files were created using software found the K2FootprintFiles GitHub repository. Users should be aware that the footprints here may differ from the WCS found in the headers of the ffi-cal.fits files. In addition, there is one known Campaign 0 FFI file for which the mission pipeline produced incorrect WCS information. The Campaign 9 FFI files do not contain WCS information at all, for this Campaign, MAST has used the footprints here for defining footprints in some of our services. Note that these include the planned Campaign 20 field, which ultimately did not get any observations before the mission ended.
Text Format
The following contain footprints for Campaigns 0-20: k2-footprint.csv | k2-footprint.json
MOC Format
MOC is a HealPix-based VO standard file format that is supported by the Aladin interactive sky atlas.
