2003 May 12+13

NAOMI in GRACE with MIT3 CCD as detector (this CCD will be used for OASIS). Used with with OASIS dichroics, OASIS feed flat + doublets, MITLL3 CCD at position of OASIS (and SBIG simplexing camera fed by deployable flat just in front of MITLL3). Field ~ 1 arcmin. The new NCU, ADC, dichroic changer and OASIS were not present. All objects were observed at low airmass.

Total time used: 0.8 nights (the remainder was for INGRID tests + service, in poorer seeing).

Time used:

Conditions: 0.6 - 0.8 arcsec seeing during the tests.

Observers: Chris Benn, Ilona Soechting at night; Sebastian Els, Tom Gregory for daytime setup.

2002 Mar 31

The aim was to test Tom's sky baffle, fitted on the WFS pickoff mirror, close to the focal plane. Bad weather, but reduction in intensity of light recahing wfs from the illuminated dome was a factor ~ 10, as expected for a 2.5-arscec aperture (vs ~ 9 arcsec previously). The size of the aperture was also confirmed by imaging it with the WFS doublet.

2001 Sep 1-4 + 27-30

NAOMI set up with TEK1 CCD as detector, fed via Laser Components R or I dichroics, to assess performance in the optical (for future use of NAOMI with OASIS).
