UniformSpaceDistributionSingleLuminosity

class agabpylib.simulation.parallaxsurveys.UniformSpaceDistributionSingleLuminosity(numberOfStars, minDistance, maxDistance, meanAbsoluteMagnitude, stddevAbsoluteMagnitude, surveyLimit=inf)

Bases: ParallaxSurvey

Base class for simulated parallax surveys in which the stars are distributed uniformly in space between a minimum and maximum distance and with all stars having an absolute magnitude draw from the same Normal distribution.

meanAbsoluteMagnitude

Mean of Gaussian absolute magnitude distribution

Type:

float

stddevAbsoluteMagnitude

Standard deviation of Gaussian absolute magnitude distribution

Type:

float

Methods Summary

apparentMagnitude_lpdf(m)	Calculate the natural logarithm of the analytical probability density function of the apparent magnitudes in the simulated survey.
generateObservations()	Generate the simulated observations.

Methods Documentation

apparentMagnitude_lpdf(m)

Calculate the natural logarithm of the analytical probability density function of the apparent magnitudes in the simulated survey. This can be derived from the know parallax and absolute magnitude PDFs.

Parameters:

m (float or float array) – The apparent magnitude(s) for which to calculate the PDF.

Returns:

logPdf – The value(s) of ln(PDF).

Return type:

float or float array

generateObservations()

Generate the simulated observations.
