Product Name
Vibration Correction Frequency Offset Indices
Mission
COBE/FIRAS

Description

The coefficients of the vibration correction terms are contained in the calibration model solution. The vibration frequencies are based on an FFT length of 720.

The first two lines are primary offsets for the following channels and scan modes:

RHSS RHSF RHLF RLSS RLFS/FL RLLF 
LHSS LHSF LHLF LLSS LLFS/FL LLLF

The next two lines are secondary offsets in the same order.
