At the beginning of 2006 a mistake was made in CASSINI reconstructed 
CK production: DOY 42 was missed. 

This caused the DOY numbering in the file names be shifted by one -- 43, 48, 
53, 58, and 63 instead of 32, 37, 42, 47, 52, 57.

This mistake was caught and the files were re-delivered with the correct
names which made these files redundant.
