Specim

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. (source: phone chat with Bill, 6/Nov/2007)
