Following are some notes on the information content of this FITS file. To get a more complete picture of the gravity- and soak temperature-induced solid body & figure distortions, these are contained in the 6 columns labeled _{tx,ty,tz,rx,ry,rz} of the table extension labled _solidbody and the zernike expansions given in the table extensions labled _S{1,2}_zernexp. The first 3 columns of each extension give the input conditions: TCS_elevation, CAM_rotation & Soak_Temp, where a value of -99.00 indicates that the perturbation was turned off. This gives (for no soak temperature) displacements of L1 surface 1 when gravity is along the axis in question: (tx,ty,tz)=(-323.3,-331.6,-36.8)um zeros are kept in the tz, rx and ry columns for the solidbody extensions because these are picked up as terms in the zernike expansion, separately (2 surfaces for each element).
