34-channel ROSAT PSPC response matrices available at the OGIP CALDB



      34 channel ROSAT PSPC detector redistribution matrices available
      ****************************************************************

The following 34-channel detector redistribution & response matrices 
have been delivered to and installed in the OGIP CALDB:

34 PI channel detector redistribution matrices
----------------------------------------------
/caldb/data/rosat/pspc/cpf/matrices/pspcb_gain1_34.rmf
				    pspcb_gain2_34.rmf
				    pspcc_gain1_34.rmf

On-axis 34 PI channel response matrices (including the on-axis effective areas)
--------------------------------------------------------------------------------

/caldb/data/rosat/pspc/cpf/matrices/pspcb_gain1_34.rsp
				    pspcb_gain2_34.rsp
				    pspcc_gain1_34.rsp

Please note that NONE of the matrices represent any improvement of the 
PSPC spectral calibration, and are simply (appropriately) compressed 
versions of the 256-channel matrices announced last week.

Further details on the new naming scheme etc can be found in 
        /caldb/data/rosat/pspc/cpf/matrices/README

The ROSAT GOF will/may be announcing these changes to all ROSAT GOs via a 
ROSAT Status Report in the near future.
