Functions
	catchWarnings (_func=None, *, warns=[])
	typeSafePandasAssignment (target, source, columns, default_dtype=np.float64, int_fill_value=0, force_int_to_float=False)
	compute_optimized_periodogram_grid (x0, oversampling_factor=5, nyquist_factor=100)

Detailed Description

Plugins for use in DiaSource summary statistics.

Output columns must be
as defined in the schema of the Apdb both in name and units.

Function Documentation

catchWarnings()

catchWarnings	(		_func = None,
		*	,
			warns = [] )

Decorator for generically catching numpy warnings.

compute_optimized_periodogram_grid()

compute_optimized_periodogram_grid	(		x0,
			oversampling_factor = 5,
			nyquist_factor = 100 )

Computes an optimized periodogram frequency grid for a given time series.

Parameters
----------
x0 : `array`
    The input time axis.
oversampling_factor : `int`, optional
    The oversampling factor for frequency grid.
nyquist_factor : `int`, optional
    The Nyquist factor for frequency grid.

Returns
-------
frequencies : `array`
    The computed optimized periodogram frequency grid.

typeSafePandasAssignment()

typeSafePandasAssignment	(		target,
			source,
			columns,
			default_dtype = np.float64,
			int_fill_value = 0,
			force_int_to_float = False )

Assign from a source dataframe to a target dataframe in a type safe way.

Parameters
----------
target : `pd.DataFrame`
    Target pandas dataframe.
source : `pd.DataFrame` or `pd.Series`
    Grouped source dataframe.
columns : `list` [`str`]
    List of columns to transfer.
default_dtype : `np.dtype`, optional
    Default datatype (if not in target).
int_fill_value : `int`, optional
    Fill value for integer columns to avoid pandas insisting
    that everything should be float-ified as nans.
force_int_to_float : `bool`, optional
    Force integer columns to float columns? Use this option
    for backwards compatibility for old pandas misfeatures which
    are expected by some downstream processes.
