SOFIE signal changes due to FOV drift using spacecraft pointing reduces SNR margins: 

SOFIE signal changes due to FOV drift using spacecraft pointing reduces SNR margins *Lockdown was moved within a radius of 2.5 arcmin and the signal change for 12 arcsec drift (over 10 / seconds / 25 km) was calculated. Numbers shown are the worst case for all possible lockdowns. Note: the drift induced dV signal uncertainty is the error in the corrected signal considering a regression to the signal change vs FOV drift, the measurement noise (from calibration), and the pointing error (from calibration). This analysis captures all of the errors and is our CBE.
