Set scans after firing cal=5.
Aerostat down at the beginning of the run. Remy radar (1270/1290) not transmitting.
Pta Salinas in mode C (1295, 1303, 1310, 1320. Note: Pta Salinas is always present, and has
been in mode C for the last 4 nights). RFI at 1246. Aerostat radar RFI appeared
at 21:38 AST at 1242, 1256 -- stronger than Pta Salinas. Smooth observation.

A variety of RFI behaviours tonight. Rubbish all over the place at first, the
following associated with Puntas Selinas: very strong spikes at 1242 and 1256,
medium broad RFI at 1275 and below 1230, weak broad RFI between 1265-1270, and
1305-10, and very weak broad RFI at around 1290. To these were added the
moderate narrow RFI at 1295, 1304, and 1310 as seen last night, plus 1320 from
San Juan, and also the satellite interference between 1243-51. All Puntas
Selinas RFI disappeared during scan 6 and reappeared between scans 9 and 10.
From scan 15 onwards it became much weaker with only the two main signals at
1242 and 1256 evident. The satellite RFI also became much weaker.

Trouble-free observing. Remarkably little interference below 1295, only the
broad, weak satellite signal between 1245-1251 which faded away towards the
end of the run, and the 60MHz birdie drifting around. No Puntas Selinas!
Above 1295, four narrow moderate strength signals at 1295, 1304, and 1310 as
seen last night, and 1320, plus the 60MHz birdie. Beautiful data between 1260
and 1295, virtually uncorrupted for the whole run. Some satellite
interference below 1230 towards the end.

Cleaner than usual below 1260 with only two Puntas Salinas signals, at 1241
and 1256. However, dirtier than usual above 1260 with moderate interference
at 1295, 1304, 1310. Also 1320 (San Juan). Moderate and broad at 1275, weak
and broad at 1245, 1266, and 1307. Smooth startup and observation otherwise.

Very strong aerostat radar for all of the run. 1 scan per file; 1 cal per scan.
Not very useful. Livedata was
run on a dataview window after each bdfits file was closed.

Again unlucky with wrap at start. Very strong Puntas Salinas radar for first
half and very last bit of run. Why do we only get scheduled for 1 hr? This
is so inefficient!
1 scan per file; 1 cal per scan.

Setup very smooth, but lost a heap of time when telescope had to unwrap.
1 scan per file; 1 cal per scan.

Bug in script - lost around 10 mins at startup. Tried using 5 scans per cal,
but in the end went back to 1 cal per scan and 1 scan per file. Overhead
is mostly in moving antenna.
Strong interference from yesterday not present (ringing was introduced by mean
processing).

running smoothly, LST in CIMA script has been fixed.
Strange ringing from scan 16 on or so. Goes away with hanning smoothing.

the first data sets where the orientation and cals are consistently correct.

Lots of problems starting up. Only after restarting WAPPS did we collect
good data (see logs). Firing of calls seems to work now, too.

Even though we set calsecs to 2 and then 3 seconds, we only get a 1 sec
cal firing. Only at the end (last FITS file), we managed to get 4 sec
consecutive calls by firing them using the "start cal" button.
This is an open problem to be solved.

Test of new CIMA script: start new FITS file after
every 5th scans. Fire cal at end of each scan. Temporary fix of paralactic
angle. Cal fires only for one second, even though calsec=3 in script.

new CIMA method:
telescope commanded to track ra/dec and then
to minus the siderial rate in ra. The observing is commanded
to begin at the same time as the rate is applied. Seems to work!
(at least if we trust what is in the header).

after fixes to CIMA script. Method:
antenna commanded to track ra/dec. When its there,
tracking rate commanded, wait for on-source, and start taking data.
There are still pointing problems.
