All of the long cadence data from Data Release 25 has now been made available through KASOC. Have a look at the documentation to see what the changes are, compared to the earlier DR24 release.
The short cadence data from K2 campaign 6 is now available through the "Data Search" page.
Note that this is the first (and only) set of short cadence data not affected by the pixel calibration issue.
All K2 campaign 6 long cadence data is now available in KASOC under "Data Search". This release also contains superstamps of several Trojan asteroids, which can also be found as a combined bundle under "Bundles".
The short cadence data for campaign 6 will be made available in a couple of weeks, to allow the pixel calibration issue described earlier to be resolved.
