Observing Setup
On 2003 February 22, Scott Ransom and Glen Langston made observations
at 820 MHz with the GBT and Prime Focus 1 receiver.
The system was set up for dual circular polarization observations.
The 240 and 80 MHz Receiver filters were used.
The IF Rack optical drivers 1 and 3 were used. Converter modules
1 and 5 were used with converter filters 1 and 5.
The spectrometer was set up in the 800 MHz wide, dual polarization,
single quadrant mode. The spectrometer controled the noise diode
switching at 4 Hz rate and three 20 second integrations were obtained.
The data were taken while the GBT was pointed towards pulsars PSR1220-15
and PSRJ1713+0747,
but the pulsars were not detected in these observations.
For these tests, the adopted noise diode calibrations value was
3.675 K, for both Left Circular and Right Circular Polarization.
This is the average of the liniear X and Y polarization values
(2.72 and 4.63 K respectively).
