Detectors

class gdt.core.detector.Detectors(value, names=None, *, module=None, qualname=None, type=None, start=1, boundary=None)

Bases: Enum

Detector base class containing the name/number mapping and the pointing direction in spacecraft coordinates.

When inheriting this base class, each detector will be a 4-tuple defined as a class variable, with the class variable name represented as the short name of the detector. The 4-tuple values are the full detector name, the corresponding detector number, and the detector azimuth and zenith.

Example

>>> class MyDetectors(Detectors):
>>>     mydet0 = ('MyDetector0', 0, 10.0, 50.0)
>>>     mydet1 = ('MyDetector1', 1, 0.0, 30.0)

Parameters:

• full_name (str) – The full detector name

• number (int) – The detector number

• azimuth (float) – The azimuth of the detector normal

• zenith (float) – The zenith of the detector normal

Attributes Summary

azimuth	The azimuth of the detector normal
elevation	The elevation of the detector normal
full_name	The full detector name
number	The detector number
zenith	The zenith of the detector normal

Methods Summary

from_full_name(full_name)	Create a Detector from the full detector name
from_num(num)	Create a Detector from an index number
from_str(value)	Create a Detector from a short string name
pointing()	The detector pointing in azimuth and zenith
skycoord(frame)	Return an Astropy SkyCoord of the detector pointing in the SpacecraftFrame.
