| 52 | | 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) |
| | 52 | Eagle uses a 1024x1024 CCD, but only the middle ~504 spectral pixels are used in normal operation (representing the range from ~390nm to ~950nm) and may be spectrally binned by 2 (giving 252 bands). |
