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).
The real magic is inside
scripts/analysis/clever.py. To analyse the π Sco
data, run the following command in any
% ./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))
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
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.
