We're continuing to move forward with making sense of the H1SPIH23 QPD calibration, and are craving a place to store the calibration into ISI displacement that's after the conversion to normalized spot displacement (QPD_{A,B}_{PIT,YAW} banks) but before the decoupling matrix that converts the QPD basis into the ISI basis (QPD2CART). Here's the model prep for installing 4 new filter banks (QPD_{A,B}_{PIT,YAW}_CAL) upstream of the matrix, and storing the output into the frames at 2048 [Hz].

Screenshot #1: The new blocks in the SPI_LIBRARY > HJK > OL block.
Screenshot #2: Adding the new channels in the DAQ channel list at the SPI_LIBRARY > HJK level.
Screenshot #3: Visual aide showing the QPD portion of the SPI overview screen, prior to installing these changes.
Screenshot #4: Visual aide showing the MEDM infrastructure prior to this model change.

"Why don't you just put the calibration in the QPD_{A,B}_{PIT,YAW} banks?" Because we don't want to lose the usual visual aide of the normalized spot position XY scatter plot that shows the centering of the QPD as everyone is used to seeing it.
"Why don't you put the calibration in the ISIOUTF banks?" We're anticipating the need to put some sort of "normalizing" gain that's tailored to the individual ISI, and some anti-aliasing filters in this bank, so we want to keep these conceptually different.

Library part changed committed to userapps/spi/common/models/SPI_LIBRARY.mdl as of rev r35940. The model change has been successfully test compiled on the h1build machine.
