everest.standalone.DetrendFITS(fitsfile, raw=False, season=None, clobber=False, **kwargs)

De-trend a K2 FITS file using everest.detrender.rPLD.

Parameters:

• fitsfile (str) – The full path to the FITS file
• aperture (ndarray) – A 2D integer array corresponding to the desired photometric aperture (1 = in aperture, 0 = outside aperture). Default is to interactively select an aperture.
• kwargs – Any kwargs accepted by everest.detrender.rPLD.

Returns:

An everest.Everest instance.

everest.standalone.GetData(fitsfile, EPIC, campaign, clobber=False, saturation_tolerance=-0.1, bad_bits=[1, 2, 3, 4, 5, 6, 7, 8, 9, 11, 12, 13, 14, 16, 17], get_hires=True, get_nearby=True, aperture=None, **kwargs)

Returns a DataContainer instance with the raw data for the target.

Parameters:

• fitsfile (str) – The full raw target pixel file path
• clobber (bool) – Overwrite existing files? Default False
• saturation_tolerance (float) – Target is considered saturated if flux is within this fraction of the pixel well depth. Default -0.1
• bad_bits (array_like) – Flagged :py:obj`QUALITY` bits to consider outliers when computing the model. Default [1,2,3,4,5,6,7,8,9,11,12,13,14,16,17]
• get_hires (bool) – Download a high resolution image of the target? Default True
• get_nearby (bool) – Retrieve location of nearby sources? Default True
