Imager

class telescopy.Imager(plate_scale=None, seeing=None, binning=None, quantum_efficiency=None, gain=None)

Bases: object

Container for an imager.

Parameters:

plate_scale : Quantity

Plate scale of detector in units of arcsec (per pixel)

seeing : Quantity

Astronomical seeing at time of observation

binning : int

Pixel binning factor

quantum_efficiency : float

Quantum efficiency of the detector

gain : float

Gain of the detector (e-‘s per ADU)

Methods Summary

counts(telescope, target, exposure_duration, …)	Number of ADU detected by the detector.
image(telescope, target, exposure_duration)	Generate an image of target observed by telescope.

Methods Documentation

counts(telescope, target, exposure_duration, filter)

Number of ADU detected by the detector.

Parameters:

telescope : Telescope
