Dear IGS Colleagues:

There has been a change of external clock for the OPMT station located 
in Observatoire de Paris, France. The OPMT station is now connected to a 
KVARZ active H-Maser, labeled 890, through a completely new distribution 

But this was not a smooth change, as due to unexpected problems it 
finally took almost two days of measurements to achieve it. So please 
note that the OPMT Rinex files of DOY 113-114 (April 23-24, 2007) are 
highly incomplete and probably partially corrupted. Be careful in the 
case you would process those days of data.

We are providing elsewhere a new Site Log for OPMT, taking into account 
this external clock change.

Best regards.
P. Uhrich
