Dear colleagues,

it seems that there was a typo in our previous mail to the IDS 
Analysis Forum, concerning the estimated ENVISAT SRP coefficient.

Using the standard IDS macro-models, the estimated SRP coefficients 
for IGN, using the GIPSY/OASIS software are in fact :

ENVISAT = 1.02
JASON = 0.92
SPOT-2 = 1.08
SPOT-3 = 1.08
SPOT-4 = 1.13
SPOT-5 = 1.03 (0.86 after 2008/014 (*))
TOPEX = 1.03 (0.96 before 1993/208)

(*) = when not using the 40 degrees re-orientation of the SPOT-5 solar panel

Best regards
Pascal
