BCU SX debugging

15:00: we start to check the behaviour of the SX BCU. We notice that the main issue is when the Pyramid slopes are enabled. On DX we measure slopes between +/-1, while on SX they reach 60. Probably due to low light values.

When we close on SX we get duplicated slopes on ARGOS BCU.

• Setting Pyramid to BIN2 the frame counter gets weird numbers (order of 10^6) while working with BIN4 the framecounter is 0.

We try a direct loop between FLAO and AdSec through fiber splitter. Optical loop data is decimated by 1.

Then we try to disconnect one of the 2 outputs of the fiber splitter, going directly to the AdSec. This seems to help: we see anymore the duplicated slopes and the ARGOS BCU stays alive.

SDSS J13432.85+415503

23:00: We point to Nomad 279645, ~MAG14, we setup for Pyramid.

23:38: we close the first loop but we fail,

Then we have to go back to Zentih, we have condensation on LUCI1 entrance window.

00:00: back on sky.

Probably 1.5 on TT is too high, we try to decrease the TT gain:

Same target, new pointing, we try binocular. We fail...

1:50: we must close, humidity >95%...

SDSS J1723+3411

3:00: back on-sky. Start too dim, sky getting bright. We fail...

SDSS J1958+5950

3.50: residual of binocular collimation prevent us to find the guide star... we try to clear out previous collimation and start from scratch...
