mismatch between output file format and documentation

[saigrain]

The documentation says the FLUX column in the output files is the K2SC-detrended flux, but as things stand at the time of creating this issue it is actually a copy of the input flux. We should update the documentation or modify the writer in k2io.py (I vote for the former).

flux column in output files

Hi, is this still an ongoing issue? I'm trying to run the code on a recent campaign, and am noticing that the "detrended" flux usually has a lot of signal in it - I initially thought the detrending was failing, but it might actually be this issue.

Hi Stephanie I'm afraid so! We need to update the readme ! In the k2sc output files the flux column is the raw (input) flux, while trposi and trtime are the position dependent (systematics) and time dependent (variability) parts of the model. To get a systematics corrected light curve subtract trposi from flux (you may wish to remove the median of trposi first). To get a detrended light curve also subtract trtime. Cheers Suzanne

Hi Suzanne,

OK, thanks for the info! I'll update my code for the new outputs.

Cheers,
Stephanie
