... In this case, because polarimetry is not currently possible with the 3-mm system, only task mfcal is needed to perform bandpass and antenna calibration. ... This section outlines an alternative calibration approach exploiting the dual frequency bands of the ATCA. ... Unlike the approach of Chapter 11 , the approach described here does not split the data into separate single source, single frequency files before calibration. ... Input multi-source, dual-band dataset. select=source(1921-293) . ...

... The old cal values were only measured at 2380 Mhz (probably around 1995). ... When this was done the cal values for the 2 polarization's were switched (rather than being remeasured). ... We used the sky/absorber technique to measure the cal values. ... The Trcvr and Tsky + Tscattered were adjusted so that the Tcal from sky, absorber, and skyAbsorber ratio gave consistent results. ... The Cal value measured from the sky absorber ratio was then used for the cal values. ... This will lower Tsys by 5%. ...

... Change to COS FUV Pulse Height Filtering to Lower the Observed Dark Rate . ... Changing Programs & Resolving Problems . ... FUV HV History . ... 99% of source counts while removing approximately 20% of the observed dark counts. The actual amount of the dark rate reduction depends on the PHD of the dark counts in each observation, which varies between observations and with solar cycle activity. Because of the incredibly low dark rate on COS, the effect on most observations is very small. ...

An example of the AKR (Auroral Kilometric Radiation) recorded by the POLRAD radio-spectro-polarimeter. The 3 perpendicular components of the electric field are presented in the range from 4 kHz to 1 MHz , while crossing the morning sector of the auroral region (3.00 - 5.40 MLT) at the altitudes from 14441 to 18392 km. The lower limit of the AKR was at 150 kHz, while the maximum power was received at a typical range from 200 to 400 kHz. ...
