ExoFOP-K2 Campaign 9 Contributed Data

The Kepler Primary Mission ended in 2013 when two of the observatory's four reaction wheels ceased to function. The Kepler Mission was reborn as the K2 Mission, which ran for an additional five years.

K2 Campaign 9 (K2C9) was executed April 7 to July 1, 2016 to study gravitational microlensing events. The Campaign 9 microlensing experiment involved the Kepler spacecraft observing in the +VV direction at fields toward the Galactic bulge. The program's aim was to simultaneously observe gravitational microlensing events with K2 and from Earth with ground-based telescopes in order to see a parallax effect in the shape and time of the lensing event.

As K2C9 was not driven by pre-identified targets, the Exoplanet Follow-up Observing Program's (ExoFOP) support for the microlensing campaign was specifically tailored. The general strategy was designed in discussions with the Microlensing Science Team. The three main components were:

  • A list of all identified events in the K2 field
  • A collection of detailed information on each event
  • A graphical display of available telescope resources

The ExoFOP-K2 C9 Data Set

The event list was driven by events collected by the Las Cumbres Observatory Global Telescope Network's RoboNet, which collected events and photometry from ground-based microlensing projects. The detailed information for each event included photometry, images and modeling results. In addition, users uploaded data, model parameters, and files through the ExoFOP-K2 C9 website, which was decommissioned in 2022.

Event Selection Criteria

A targets was included in ExoFOP-K2C9 if:

  • It was located within the K2C9 overall footprint, whether or not it lies in the superstamp region.
  • (t0 - 2tE) < campaign_end and (t0 + 2tE) > campaign_start

All Events Relative to C9 Footprint

This plot provides the location of all events within the last 3 years relative to the Kepler Campaign 9 footprint.

  • Black dots indicate events that lie outside the footprint.
  • Magenta indicates events outside the Campaign duration. (An event is defined to have occurred within the campaign if [t0-2tE] < campaign end and [t0+2tE] > campaign start.)
  • Cyan points highlight events that occured during the campaign, but outside the superstamp.
  • Events in green mark targets either within the superstamp or selected as out-of-superstamp targets.

Events Outside Superstamp

This plot provides a map of all events within the campaign duration that occurred inside the footprint but outside the superstamp. It is annotated with the event names.
