K2P2: Reduced data from campaigns 0-4 of the K2 mission.

HANDBERG R. and LUND M.N.

Abstract (from CDS):

Context. After the loss of a second reaction wheel the Kepler mission was redesigned as the K2 mission, pointing towards the ecliptic and delivering data for new fields approximately every 80 days. The steady flow of data obtained with a reduced pointing stability calls for dedicated pipelines for extracting light curves and correcting these for use in, e.g., asteroseismic analysis.
Aims. We provide corrected light curves for the K2 fields observed until now (campaigns 0-4), and provide a comparison with other pipelines for K2 data extraction/correction.
Methods. Raw light curves are extracted from K2 pixel data using the "K2-pixel-photometry" (K2P2) pipeline, and corrected using the KASOC filter.
Results. The use of K2P2 allows for the extraction of the order of 90 000 targets in addition to 70 000 targets proposed by the community - for these, other pipelines provide no data. We find that K2P2 in general performs as well as, or better than, other pipelines for the tested metrics of photometric quality. In addition to stars, pixel masks are properly defined using K2P2 for extended objects such as galaxies for which light curves are also extracted.

within arcsec The VizieR photometry tool allows for easy visualization of photometry points extracted around the Simbad position from photometry-enabled catalogues in VizieR.
The search radius has to be specified by the user. It is currently limited to a maximum of 30 arcsec. It depends mostly on the precision or quality of the coordinates (SIMBAD and VizieR catalogs), the resolution of the images from which the sources were extracted, source extent, and source crowding.
Suggestions are: crowded field: 0.5 to 1.5 arcsec, 3 arcsec otherwise; uncertain coordinates (SIMBAD quality E or coordinates without reference): 5 to 30 arsec (risky!). sed-help-icon
