TessLightCurveFile

class lightkurve.lightcurvefile.TessLightCurveFile(path, quality_bitmask='default', **kwargs)

Bases: lightkurve.lightcurvefile.LightCurveFile

Subclass of LightCurveFile to represent files generated by NASA’s TESS pipeline.

Parameters
pathstr

Local path or remote url of a FITS file in TESS’s lightcurve format.

quality_bitmaskstr or int

Bitmask (integer) which identifies the quality flag bitmask that should be used to mask out bad cadences. If a string is passed, it has the following meaning:

  • “none”: no cadences will be ignored (quality_bitmask=0).

  • “default”: cadences with severe quality issues will be ignored (quality_bitmask=1130799).

  • “hard”: more conservative choice of flags to ignore (quality_bitmask=1664431). This is known to remove good data.

  • “hardest”: removes all data that has been flagged (quality_bitmask=2096639). This mask is not recommended.

See the TessQualityFlags class for details on the bitmasks.

kwargsdict

Keyword arguments to be passed to astropy.io.fits.open.
