Dear all,
For some yet unknown reason, the Precise Orbit Determination system of the
operational GRAS processing went through a reset this morning; accordingly,
bending angle data was flagged as being degraded between 01:42 and (about)
06:00 UTC this morning. Our monitoring indicates that the degradation was only
minor, with upper level bending angle biases being slightly larger than usual
(in the order of 4-5 microrad in the 60-80 km altitude range).
data quality is back to normal by now.
We apologize for any inconvenience this may have caused.
Christian.
