prior to the reordering, old ITM data files were under the path

/data/ITM/h1hwsmsr/ITM[X,Y]/GPS_START_TIME

where GPS_START_TIME is of the format NNNNN00000 (each directory spans 100,000 seconds, about 27 hours).

Each ITM[X,Y] directory contains about 0.6TB of data.

These old GPS directories were moved into the new locations where current data is being written:

/data/H1/ITMX_HWS/

/data/H1/ITMY_HWS/

Note that there are still two old data directories under /data/ITM/ITM[X,Y]/1142800000 but these directories also exist in the new area so I cannot do a simple directory rename.

/data holds 1.7TB of data, of which 0.6TB is old ITMX, 0.5TB is old ITMY, 0.6TB is new data. The new data is split over the four cameras: ITMX=209GB, ITMY=50GB, ETMX=200GB and ETMY=200GB
