Details of the jitter engineering parameters used in the present analysis.

Parameters Meaning
v2_dom Dominant guide star V2 coordinate
v3_dom Dominant guide star V3 coordinate
v2_roll Roll FGS V2 coordinate
v3_roll Roll FGS V3 coordinate
si_v2_avg Mean of jitter in V2 over 3 s
si_v2_rms Mean of jitter in V2 over 3 s
si_v2_p2p Peak-to-peak jitter in V2 over 3 s
si_v3_avg Mean of jitter in V3 over 3 s
si_v3_rms Mean of jitter in V3 over 3 s
si_v3_p2p Peak-to-peak jitter in V3 over 3 s
ra Right Ascension of aperture reference
dec Declination of aperture reference
roll Position angle between north and +V3 axis
limbang Angle between V1 axis and Earth limb
los_zenith Angle between HST zenith and target
mag_v1 Magnetic field along V1
mag_v2 Magnetic field along V2
mag_v3 Magnetic field along V3

Notes. The parameters from v2_dom to si_v3_p2p are tabulated in arcseconds. The parameters from ra to los_zenith are tabulated in degrees. The magnetic field strengths tabulated in the last three rows are tabulated in Gaussian measures.
