project TPTCSOOF_061129

Log begun by FG (data located on tape-0004)

Gain cal data for KA receiver using the CCB and comparisons of OOF models.

A routine was set up (see file ccb_ptcs_setup.py) "doseq(source)" which does the following:

• a. set zernicke model to 2005WinterV2
• b. configure with "ccbbothcalslong.conf"
• c. peak/focus
• d. configure for ccb nods with "ccbAXL.conf"
• e. do a nod using Brian's "dotrajectory"
• f. set zernicke model to 2005WinterV3
• g. do a nod
• h. turn off zernicke model
• i. do a nod

The sequence was done first on 3C147, then on 0927+3902 which was at a low elevation. Tipping scans next.

Then repeated sequences on 3C84 starting just before transit.

Queued up the following, starting about 11 pm

1. sequences on 3C84 -- should end about 1 AM sequence on 3C147 (about 10 min)
2. seq on 3C84 - should end about 3 AM (estimated elevation about 55) two nods -- takes about 20 min.
3. seq on 3C84 - should end about 5 AM sequence on 3C147
4. seq on 3C84 should run until 7 AM

Log continued by RP:

When I arrived, telescope was observing 3C84 at 12 deg elevation

553-7    3C147      p/f        33deg, fits look good
558        "        V2         very ratty, 100 counts?

576        "        None       " ~300 counts

Keep going with 1642+3948 as it rises to 40deg for scan 600 at 8:05am

N.B. This experiment would be impossible without true beamswitching!! The weather looks really pretty bad, yet the data quality looks pretty good. Good choice to switch to Ka-band.

Overcast and low wind is better weather than clear and windy!

We should be able to process this as a CCB pointing scan.
