Ed modified IPD.C to have auto-level control and up to 4X photon multiplicity. However, PMAP crashed during write - so no obs. Today, I added 1 ms delays after each fwrite of pmap data, plus stopped disabling interrupts during the write. Daytime tests at PFRR suggest this may be more stable, but we'll see...
