K2 TSP Research Project

Supervisors: Tim Bedding, Daniel Huber, Simon Murphy
Institution: The University of Sydney

A research project to see if it is possible to do meaningful photometry on B star contamination of Kepler K2 postage stamps. Specifically, we focus on examples in campaign 2, but create general techniques which can be applied to any other campaign (or to astronomy in general).

Usage

The real magic is inside scripts/analysis/clever.py. To analyse the π Sco data, run the following command in any *nix shell:

% ./scripts/analysis/clever.py --csv \
	-mf 400 -m data/pi_Sco/1.203442993/ap_203442993.txt -d 1 \
	-s pi+analysis.csv -t data/pi_Sco/1.203442993/xy_203442993.csv \
	data/pi_Sco/1.203442993/ktwo203442993-c02_lpd-targ.fits
% ./scripts/post/lc.py --no-title -w 1.2 -fp 1.570103 \
    <(./scripts/post/highpass.py -w 401 -o 6 -sc 50 -ec -580 pi+analysis.csv) \
	<(./scripts/etc/mag2flux.py -i \
		<(./scripts/etc/phase2time.py --period 1.570103 --offset 2452025.96 data/pi_Sco/shobbrook_phase.csv))

π Sco

This is an example of our analysis usnig aperture analysis, using EPIC 203442993. This photometric analysis mirrors ground-based surveys of π Sco and has an incredible trendline.

Where do I sign cite?

A paper is currently in the works, so there's nothing to cite quite yet. It'll hopefully all be done and ready to publish by early 2016 2017. Watch this space to read the paper once it's published.
