Oe-On fringefit done using "-P XR+YR" in fourfit. -Logfile pressure values overwritten by updateLogPressureData.py; The change in pressure w.r.t original wx value (from pressure sensor at OSO weather station) is P_new = P_ref * (1 - 0.0000226*(h - h_ref))^5.225 [H Berg. Allgemeine Meteorologie: Einfuhrung in die Physik der Atmosphare. Dummler, 1948.] where P_ref is the original wx value, h is the height of On (59.3 m), Oe (53.2 m) or Ow (53.2 m), and h_ref is the height of the OSO pressure sensor (46.6 m). The approximate changes with respect to the original wx values (now modified) are: On = -1.5 hPa Oe = -0.8 hPa Ow = -0.8 hPa. -Submitted vgosDb contains 3 wrappers: v1: vgosDbMake v2: vgosDbCalc v3: vgosDbProcLogs +STATION_NOTES ONSALA60 (On/X): Applied manual pcal. Pcal turned off to avoid cross correlating pcal signals to Oe. Cable cal on and present in log. ONSA13NE (Oe/S): Ok. ONSA13SW (Ow/T): Did not participate due to control problems. +DROP_CHANNELS On-Oe: X00UR/X/Y due to RFI. +MANUAL_PCAL On +CHANNELS Channels: X00LX/Y = band|channel#|sideband|polarizations|notes X00UR/X/Y freq@8213.99/bw@16.0 X01UR/X/Y freq@8253.99/bw@16.0 X02UR/X/Y freq@8353.99/bw@16.0 X03UR/X/Y freq@8513.99/bw@16.0 X04UR/X/Y freq@8733.99/bw@16.0 X05UR/X/Y freq@8853.99/bw@16.0 X06UR/X/Y freq@8873.99/bw@16.0 X07UR/X/Y freq@8933.99/bw@16.0 +CLOCKS Clocks: OSO Station fmout-gps Used Rate Comments [usec] [usec] [sec/sec] On -26.639 -0.188 0 Reftime 2019y120d12h00m0s Oe -26.460 +3.35 0 Reftime 2019y120d12h00m0s NOTE: Correlated before knowing about peculiar offsets; hence only the relative time is correct in these data. +QCODES Qcod 0 1 2 3 4 5 6 7 8 9 A B C D E F G H N Tot ------------------------------------------------- SX:X 0 0 0 0 2 5 5 9 48 923 0 0 0 0 0 0 3 0 0 995 ------------------------------------------------- Tot 0 0 0 0 2 5 5 9 48 923 0 0 0 0 0 0 3 0 0 995 +SNR_RATIOS Not applicable due to incorrect SKED prediction due to incorrect SEFDs for antennas at skeduling time.
