Subject: SUMER Radiometry Programme

Dear colleagues,

I am sorry to announce an error in the radiometry programme, which Udo
Schuehle has just found. The error is in the new magnification programme
and occurs for detector B and in second order only. The spectral resolution
element came out twice as large as it should be. The new programme was put into 
the software tree on 26 November 1998 and was updated today with a correction
of the error. This error had an effects on radiometry outputs only for
spectral radiances (per Angstroem), but not for line radiances. 
So, if you have done any calibration work involving spectral radiances 
and detector B in second order recently, I am afraid you have to check your 
results. I am sorry for the inconvenience.


With best regards,
Klaus Wilhelm
