Oe-On fringefit done using "-P XR+YR" in fourfit. On-Ow fringefit done using "-P RX+RY" in fourfit. Oe-Ow fringefit done using "-P I" 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): Applied manual pcal. Pcal and cdms system broken. +DROP_CHANNELS Baseline: Channels dropped On-Oe/Ow: X00UR/X/Y due to RFI.
