3rd Jan 2017: K2 campaign 10 data available

Data from campaign 10 of K2 has been made available on KASOC. The data release notes have not yet been made available, but we will provide it as soon as it is available.

Please note that there are a few unique features in the C10 data:

  • The first six days of data, dubbed C10.1, were collected with a pointing error of 3.3 pixels from the nominal field-of-view, so they were only processed through CAL to make "Type 1" target pixel files. Among other things, this means that there are no light-curves produced by the K2 Science Office.
  • The remainder of the campaign, dubbed C10.2, was processed through the entire photometry pipeline, creating "Type 2" target pixel files and long-cadence light curves.
  • Module 4 was lost part way through C10.2, which powered off the photometer and produced a 14-day data gap.

14th Dec 2016: Scheduled downtime

Tomorrow (15/12-2016) we will be doing some scheduled maintenance of our systems, so the KASOC website will be unavailable for a few hours. We apologize for the inconvenience.

13th Dec 2016: Reprocessed data for K2 C1

Reprocessed data for K2 Campaign 1 (Data Release 14) is now available for download.

This release corrects the short cadence pixel calibration bug previously described in the Global Erratum for Kepler Q0-Q17 & K2 C0-C5 Short-Cadence Data (KSCI-19080). The new release also includes lightcurves for all long cadence data, plus improvements to the target pixel files.

Please have a careful read of the Data Release Notes.

2nd Feb 2017: K2 Campaigns 14, 15 and 16 Director's Discretionary Targets program

A small percentage of the available K2 pixels in each campaign may be allocated by the K2 Guest Observer (GO) Office Director as Director's Discretionary Targets (DDTs). The primary utilization of DDT programs is in support of community-proposed requests that are based on exceptional, time-critical observing opportunities that cannot be …
