modest.spacecraft.chandra module

class modest.spacecraft.chandra.Chandra(userData, ureg, tStartOffset=0)

Bases: object

class modest.spacecraft.chandra.ChandraDetector(eventsFileList, userData, ureg)

Bases: object

getPhotonMeasurement(index)

FOV = None

Detector field of view in degrees (half-cone angle)

TOA_StdDev = None

Standard deviation of arrival time measurements. Depending on user input, this can be modeled as a uniform distribution (over the time resolution of the detector) or as a normal distribution with standard deviation specified by user.

area = None

Detector effective area in square centimeters

photonEnergyVar = None

Stores the expected variance of the photon energy measurement. Since photon energy measurements are truncated to integers we use the uniform distribution

photonXUnits = None

Units of photon x angle of arrival measurements

photonYUnits = None

Units of photon y angle of arrival measurements

pixelResolutionX = None

Pixel resolution of the detector’s x angle of arrival measurements

pixelResolutionY = None

Pixel resolution of the detector’s y angle of arrival measurements

timeConversionFactor = None

Factor to multiply arrival times by to get correct values in units of seconds

timeOfArrivalUnits = None

Photon time-of-arrival units

timeResolution = None

Photon time of arrival resolution
