Katoctin

katoctin is a package that automates multi-planet search in archival K2 light curve data. The algorithm is based on Transit Least Squares (TLS) to find planet transits in K2 light curves. The code uses a custom detrending algorithm based on Savitzky–Golay filtering to normalize light curves.

This is my summer project at Space Telescope Science Institute. Many thanks to Dr. Susan Mullally, who mentored me, and STScI for giving me the opportunity to create this.

planet_search

Command line script for planet search.

Usage:

planet_search [-h] (-f FILE | -s STARS) -c CAMPAIGN [-l LOG]
              [-p PROVENANCE] [-m MAX_PLANETS] [-i]

Find multiple planets around each star in the input list.

Optional arguments:

-h, --help show this help message and exit -f FILE, --file FILE   Name of a CVS file containing EPIC star IDs. -s STARS, --stars STARS   Comma-separated list of EPIC star IDs. -c CAMPAIGN, --campaign CAMPAIGN   Campaign number. -l LOG, --log LOG   File name of the log file containing results. -p PROVENANCE, --provenance PROVENANCE   Find planets using data from the specified provenance. -m MAX_PLANETS, --max_planets MAX_PLANETS   Maximum number of planets to find for each star. -i, --interactive   Whether or not to be interactive plots that allow for zooming in.

Examples:

$ ./planet_search -s 228863643 -i -c 1
$ ./planet_search -s '228863643,228867558' -i
$ ./planet_search -s '228863643,228867558' -i -c '*'
$ ./planet_search -s '228863643,228867558' -i -c '*' -m 2

fcomp

A script for comparing planet periods found as a result of planet search and saved in the summary log with periods downloaded from MAST.

Usage:

fcomp [-h] -s SUMMARY -m MAST -o OUTPUT

Compare found transit periods with known values from MAST.

Optional arguments:	-h, --help show this help message and exit -s SUMMARY, --summary SUMMARY   File name of the summary log with computed results. -m MAST, --mast MAST   File name of the mast file containing the confirmed period and data. -o OUTPUT, --output OUTPUT   File name to which to save the results of the comparison.
Examples:

$ ./fcomp -s logs/summary_log.csv -m mast_data/k2_mast.csv -o comp_results.csv
