go to check star 189301
niro align
cal large diam but easier for niro align, to be corrected as diam=1mas
We will have to be careful with the calibration

     problems of pointing
     cannot find the star anymore
     recording 2T data at 250Hz/DEST/MED (E1E2), could not find the fringe
     probably disaligned ?

Summary
-------

2 brackets on MWC275
1 bracket on MWC340, 2T mostly as fringes too faint (E1E2)
1 bracket on MWC361
