#199 closed bug (fixed)

Unable to re-interpolate nav on old level 1 HDF files

Attempting to re-interpolate the nav/scan timing on CASI data for flight 97/14 using aznav, the program seems to edit the HDF files correctly but then doesn't release the file lock (gives error "There are still open AIDs" on closing). Everything seems fine but then it causes azgcorr to hang part-way through. It is believed this is because the old data is HDF 3.3 format (rather than HDF 4) and there are compatibility problems.

Following discussions with Bill, it has been decided that the easiest way to do this is to use hrepack to update old HDFs to v4.2 before re-interpolating. There are incompatibilities between HDF 3.3 and 4 that make fixing this within aznav awkward, and given how infrequently we need to do this there's no point in spending a lot of time on it.

Closing ticket.
