So far, all, 1&3, 4&6 have been fit. Dependencies: Cal model details. Reply: Probably not. If there are no other objections, I will delete the single-shell extensions from the specified file format. 981022: objection: need individual shells, since get weighted by grating effic. prior to summing. 990219 Cal/MST are generating denser table - 70 angles, 1000 energies (and each shell?) ==> use tables instead of model.

They are modeling QE uniformity. At low energy, all noise (i.e., uniform). At higher energies, looks like: Q(E,x,y) = K * exp( -A(x,y) / lambda(E) ) A(x,y) are depeletion depths, large scale fluctuations (> 32x32 pixels). lambda(E) is absorption scale length; can possibly be parameterized in this energy range by a power-law. Mark will deliver A(x,y), lambda(E) if we want. But for BI: need empirical table of QE, as defined. He will review the ICD. Dependencies: IPI model and product delivery, use in exposure map code. Reply: consider new format or function for FI non-uniformity. Due Date: 981130 Status: pending review.
