Notes for running scans:
1. when first turning on Agilent, set initial stuff
    > cd /users/annalisa/postVent/20180718
    > AGmeasure TFAG4395Atemplate.yml
2. tweak arm alignment and offset PLL
    > sitemap (then IFO --> ALIGN and also PSL --> AUX)
    > to increase 
3. make sure X-arm is misagligned (hit '! Misalign' button for ITMX, ETMX) 
3. run scan
    > python AGfast.py startfreq stopfreq points
FSR:
    > python AGfast.py 30e6 36e6 600
car:
    > python AGfast.py 31.68e6 31.78e6 300
hom4:
    > python AGfast.py 32.27e6 32.37e6 300
hom1:
    > python AGfast.py 32.84e6 32.93e6 300
hom5:
    > python AGfast.py 33.39e6 33.53e6 300
hom2:
    > python AGfast.py 33.95e6 34.06e6 300
hom3:
    > python AGfast.py 35.09e6 35.25e6 300
4. process scan
    > l <-- this gives name of scan latest_foo.txt
    > ./processData.sh latest_foo.txt [ref.h5py] <--- optional reference argument
    this creates a .txt, .pdf file
5. to make something a reference:
    > python makeHDF5.py scandata/parsed/{current}/foo_parsed.txt scandata/parsed/{current}/foo_parsed.h5py
6. save files to scandata/{reflector,cylinder}/{parsed,unparsed}/{CAR,HOM1,HOM2,HOM3,HOM4,HOM5}{_datetime}{_parsed,_unparsed}.{txt,pdf}

Agilent notes:
1. reset Agilent: sweep = continuous, display = hold max
2. to sweep marconi:
    > python marconiSweep.py startfreq stopfreq points
3. to grab Agilent data:
    > cd data
    > AGmeasure --getdata -i 192.168.113.105
this saves it in /data as AG...txt
4. plot data
    > ipython
    > %run plotSpec.py
