Position switched observations using L-band

This is a series of scripts which combine together.

The idea here is to do the following:

1. Slew the telescope to the first source of the night
2. Configure for the DCR
3. Slew to a nearby calibrator
4. Balance the power levels
5. Run a peak scan
6. Run a focus scan
7. Configure for the spectral line observations, adding the DCR to the scan coordinator (for no great reason)
8. Slew to the first source
9. Balance the IF rack and spectrometer
10. Step through all the sources in your evening's list:
    1. Slew to a source
    2. Balance the IF rack (not the spectrometer, to save time)
    3. Take a position switched scan, NOT firing the cals
    4. stay at the off source position and take 10s of data with the cals firing
    5. repeat on the next source in the list

The files are below:

1. Script for turning off the noise diodes - caloff.py
2. Script for turning on the noise diodes - calon.py
3. The source "catalog" (not a real catalog, but an array of sources which are stepped through) - cat.py
4. The spectrometer set-up file - setup.py
5. The script for the night's run (in this script, the true path to the above files should be given after the "execfile" command) - turtle.py
