Y/DDD is year and day of year, DSS is station, RSR is the RSR used to collect the data, Lvl is the rms sample value computed at Stanford (0 would be at or near clipping), Px/No is the RSR FGAIN setting, and ATT is the RSR attenuator setting. Actual from recent experiments ------------------------------ Y/DDD DSS RSR Lvl Px/No ATT ----- --- --- --- ----- --- 4/145 26 1A -6 56 22 4/146 45 1A -9 56 31 4/146 55 1A -7 56 51 4/146 63 1B -5 64 26 4/147 45 1A -9 56 25 4/147 54 1A -6 56 27 4/147 63 1B -5 64 22 4/147 26 1A -6 56 21 4/148 55 1A -7 56 54 4/148 63 1B -6 56 49 4/149 34 1A -10 56 22 I'd prefer to keep Lvl at or below -3, but that means there's still some room for improvement in all cases. At DSS 63 it should be possible to set FGAIN = Px/No to 62; I did not actually see a Px/No as large as 60 in the data. For the northern hemisphere 34-m antennas FGAIN=53 would help; for Canberra FGAIN=50 would be my recommendation. Since Mars is still moving away, these values might be good enough to carry us through solar conjunction and to the end of the year - at which time we should start moving them back up again. Let me know if this does or does not make sense. Thanks, Dick
