optoanalysis.thermo.thermo module

class optoanalysis.thermo.thermo.ThermoObject(filepath, RelativeChannelNo=None, SampleFreq=None, NumberOfChannels=None, PointsToLoad=-1, calcPSD=True, NPerSegmentPSD=1000000, NormaliseByMonitorOutput=False)

Bases: optoanalysis.optoanalysis.DataObject

Creates an object containing some data and all it’s properties for thermodynamics analysis.

Attributes:

SampleFreq : float

The sample frequency used in generating the data.

time : ndarray

Contains the time data in seconds

voltage : ndarray

Contains the voltage data in Volts - with noise and clean signals all added together

SampleFreq : sample frequency used to sample the data (when it was

taken by the oscilloscope)

freqs : ndarray

Contains the frequencies corresponding to the PSD (Pulse Spectral Density)

PSD : ndarray

Contains the values for the PSD (Pulse Spectral Density) as calculated at each frequency contained in freqs

calc_mean_and_variance_of_variances(NumberOfOscillations)

Calculates the mean and variance of a set of varainces. This set is obtained by splitting the timetrace into chunks of points with a length of NumberOfOscillations oscillations.

Parameters:

NumberOfOscillations : int

The number of oscillations each chunk of the timetrace used to calculate the variance should contain.

Returns:

Mean : float

Variance : float
