RECTECorrector module

RECTECorrector.RECTECorrector1(t, orbits, orbits_transit, counts, p, expTime, include_transit=False)

correct the ackbar model for one directional scan observations

Parameters:

• t – time stamps of the exposures
• orbits – orbit number of the exposures
• orbits_transit – orbits in which transits/eclipses occur
• counts – observed counts
• p – Parameters objects to fit
• expTime – exposure time

Returns:

RECTE profile for correciting the light curve, best fit

count rate array, ackbar output, slope :rtype: tuple of four numpy array

RECTECorrector.RECTECorrector2(t, orbits, orbits_transit, counts, p, expTime, scanDirect)

correct the ackbar model for one directional scan observations

Parameters:

• expTime – exposure time
• scanDirect – scan direction (0 or 1) for each exposure

Returns:

RECTE profile for correciting the light curve, best fit

count rate array, ackbar output, slope :rtype: tuple of four numpy array
