IR Imaging 66 Comet images and 29 calibration star images Rec: /catalog irimag.cat Somewhere (in some file) do we need to say that only 2 of the instruments were real 2-D arrays, one was 1-D (linear scan), and one single pixel (2-D scan)? One can interpret this from the irimag.cat knowing the history of the technology, but this might be more obscure for future generations who never knew anything other than 2-D or 3-D detectors! Maybe array sizes?
