New Microwindows
Nov05 Bug found in Jacobian spectra used to compute previous set of 2RR microwindows (301-330)
Forgot to include AILS convolution so
Error analysis over-optimistic, especially at high altitude
However, quite reasonable retrievals have been obtained
Selection of new set now in progress (331-340)

Conclusions
Microwindow Selection & LUTs - complete for first 10MWs for pT, H2O, CH4 and N2O
Large pT random error at 1.5km vertical resolution dominates error budget of other species - ignored during MW selection
Random and other systematic errors for species seem acceptable, even at 1.5km resolution.
