I was just noticing that with those dimensions you files are ~2.2GB.
So the variables I used to calculate the file location (for point_lun)
are getting close to overflow. It would be better to change the
dimensions and indexes in the code I sent to type 64-bit integer:

ns=296LL ;samples
nb=492LL ;bands
nl=8000LL ;lines
nc=2L ;chunk size

That way their products will not overflow if the file is a little
larger.
