= Sensors = Most of the useful information is currently on the main ARSF website - http://arsf.nerc.ac.uk/ You can find a thesis covering the underlying principles of the Specim instruments (Eagle & Hawk) at http://www.vtt.fi/inf/pdf/publications/2001/P435.pdf == Notes of interest == Eagle uses a 1024x1024 CCD, but is spatially binned by 2 when in operation (so you get a maximum of 512 spatial pixels). This base level of 2 is "spatial binning = 1". However, when in calibration mode, the instrument returns the full data width (ie. all 1024 pixels). This must be accounted for in any calibration code.
