exclude_data(beginning=True): Removes one datapoint from the data set. If beginning is True, first element is removed, otherwise last.

diagnostic_plot(diagnostic, target, flux_interp=False): Plots the output of the interpolation

data_interp(target, step=0.1, date_low=None, date_high=None, diagnostic=None, no_reject=False, flux_interp=False)

Interpolate dataocities using Gaussian Process regression

Parameters

targetstr: Specifies as what the data is to be interpolated. Determines Gaussian Process kernel. Photometry has to contain ‘phot’ in target name.
stepfloat: Resolution of the interpolated data. Default: 0.1
date_lowint or float: Lower epoch limit of interpolation.
date_upint or float: Upper epoch limit of interpolation.
diagnosticstr or None: Path to directory where diagnostic plots are to be saved.
no_rejectbool: If True velocity fits with increasing values will not be rejected. Default: False
flux_interpbool: If True, data is converted to flux before interpolating. Exported values will be converted back to magnitudes. Only works with ‘phot’ in target. Default: False

Returns

medianfloat: median data value at date days

data_int_error_lower : float data_int_error_upper : float

return values are in m/s

datefloat: date to which the magnitudes have been interpolated
