RRL mode 1 position switching
RRL mode 2 position switching
RRL Mode 3 position switching
quick mapping mode 1
quick mapping mode 2

Double-check scripts for weekend.
data location: /home/scratch/akepley/vegas_tests/mode123_test_dec052013
Start at noon, after Frank finished. Needed to wait for gbfiler to be restarted.
Finally got access to everything around 12:30
appeared to run okay
analyzing data in GBTIDL-test
The data appeared to be okay: right bandwidth, right channel resolution. The number of integrations is correct. However, the integration time is listed as 4.9s, when I integrated for 10. Is this right?
Data looks good: right bandwidth, right channel resolution. right total number of integrations (30s in ON, 30s in OFF). Exposure time is listed as 29.9s.
ripples in tp? according to Anish, they are more apparent than in mode 2 than mode 1 because mode 2 has higher resolution. ripple coming from cable.
delF given as 91.553 kHz. Anish's latest chart has 92 kHz
exposure time is listed as 4.9s
data looks good. right BW, right delta frequency.
failed with host of VEGAS errors.
Ray fixed problem.
data looks good. BW not being shown properly. Looks like I'm getting more than 850 MHz of bandwidth (more like 1000 MHz). However, according to Anish that's expected. Low end drop off is the converter rack (0-150MHz; some may be useable). The high end is an analog filter in VEGAS (>950 MHz).
61.035 kHz spectral resolution -- close to value given in table of 61 kHz.
