    1414Details on processing the ILS/FODIS data are in the azgcorr manual (to a limited extent - we'll improve this as soon as we get the manual text..).  Basically it's an extra data vector in the HDF files, called CAils, with one pixel of upwards-looking data per downwards-looking scanline.

    16 The vector should be present in all CASI and Eagle HDFs, but will be garbage in any flight where the sensor wasn't connected (fibre optic cable from the CCD to the roof-mounted collector) and in any Eagle HDFs preceeding mid 2008 as the cable wasn't connected (may be present in some Ethiopia flights) and the processing wasn't working (fixed as of June/08, backprocessing available on request).

    1820Note that due to a bug in ENVI (?), it appears that one gets odd spiky results from directly viewing the HDF vector.  You must extract it first with:
