Problem with DR24 Short Cadence Data

The Q2--Q16 Data Release 24 (DR24) short-cadence (SC) data, which was processed with the SOC 9.2 pipeline, is incorrect and virtually unusable for projects requiring high photometric precision. The problem was traced to an error in the pipeline module that calibrates the pixels, specifically in how it handles the ...

K2 Campaigns 8, 9 and 10 Director's Discretionary Targets Program

The Guest Observer Program solicitation for K2 occurs roughly twice per year and includes a call for multiple K2 campaigns. Given the proposal review timeline, and associated data processing and archive activities, there can be a significant delay between proposal submission and final target selection for each K2 campaign. To ...

K2 Campaign 7 Science Program Available

The K2 Campaign 7 Target List has now been posted. In Campaign 7 there was a significant drop in the number of targets observed relative to previous campaigns. This drop was because the number of targets we can observe is a function of our on-board compression efficiency. The extremely dense ...
