The antiwhitening filters for POP_A_LF and REFL_A_LF did not correspond to the analog whitening on the chassis in ISC R4.

• POP_A_LF had no whitening, but the digital SFM had two antiwhitening filters engaged. I turned both whitening filters on. This makes the dark spectrum a factor of 2 or so above the ADC noise.
• REFL_A_LF had no whitening, but the digital SFM had one antiwhitening filter engaged. I turned off the antiwhitening filter. We should re-evaluate whether we want to turn on some whitening.
