PF2

Spectra from PF2: 900-1240 MHz

During commissioning of the Prime Focus receiver July 18-19, 2003, some spectra were taken with the 200 MHz mode of the ACS. Some of these illustrate the RFI situation and are shown here.

Project codes were TRFI_PF2_01 and TRFI_PF2_02.

1. Daytime, Average of scans 27-30, rotating 0-360 in azimuth at elevation = 6°

2. Night, Average of scans 31-34, rotating 0-360 in azimuth at elevation = 6°

3. Night, composite of 6 2-minute scans at az=180, el=57. Note the X-axis labels should be 900,1000,1100,and 1200 MHz, instead of -900,-800, etc. The x-axis goes from 900 to 1240 MHz.

4. 925-945 MHz. Day. Detail of plot#1.

5. 965-985 MHz. Day. Detail of plot#1.

6. 1040-1070 MHz. Day. Detail of plot#1.
