=================================================================================================== L-band RFI. Uacceptable difference in Tsys between the different channels :-(. Will check again when we have the 18cm system up. =================================================================================================== Used cl10l1-63-67-gain-rcp.log to calibrate Tcal.

The same for most experiments. =================================================================================================== es042a: RFI =================================================================================================== =================================================================================================== 6 cm: Higher Tsys than normal in RCP. Not clear why!!!! =================================================================================================== Used tl10c6on.log to calibrate Tcal.

First Tsys when we are at el=68.9 source=1803+784,180339.35,782754.4,1950.0 Second Tsys when we are at el=23.0 source=3C454.3,225129.53,155254.2,1950.0 antabfs interpolates between these values. Not good. Would it be possible to end with an calbration if we are moving the telescope a long way?? =================================================================================================== ry002a: Higher Tsys than normal in RCP. Not clear why!!!! We have an elevation limit of 6 degrees. =================================================================================================== =================================================================================================== S/X-band =================================================================================================== Used cl10sx1o-el30.log to calibrate Tcal.
