In the archive there are non-corrupt version of the files here but
they are likely the ones with the incorrect values for the errors.
For example the current copy of the file:
CFHTLS_D-85_z_022559-042940_T0004.cat was added into our archive at:
File ingest date: Tue Jun 12 10:32:13 2007 so, likely this is the
one with wrong error values.

When the replacement version of that file was provided that
replacement was found to not uncompress correctly and so we did not
replace the file with the 'corrupt' version but kept the one with the
'bad errors'.

Is the content of the files you checked correct?
