	4. Since w1 doesn't track well, we turn it off. we realized this greatly adds to turbulence since the metrology normally acts to correct turbulence in the air path. something to keep in mind on sky.		4.

	5. we have first half-night for engineering for wed/thursday (ming is here!). We hope to try to test fringe tracking and gdt on beam 3-4 and then move on to all beams!!		5. we have first half-night for engineering for wed/thursday (ming is here!).

			6. Problmes with using new backup drive for old Mirkwood. need to reformat this.
			7. Ettore got a version of the NEW MIRKWOOD working!! still some loose ends with spooler headers but the hard part is working and hope to test it also this week before we leave. see [[2010Aug:mirkwood2]]

 . hopefully tomorrow we will ahve lab fringes in b1-b2, b3-b4 early. we will test the gdt acuumulation , will get new fringe data to optimize opd map, and will test state matchine using delaylines. if we get this done we can go on sky.

			==2010 August 7==
			1. during day lab alignment, pzt on beam 3 stopped working. after an hour or two of debugging we found the extension cable had gone bad. i am in process of ordering two 2m extension cables for lemo 0s 250 (compatible with piezojena ENV 150) -- called Z-002-02.
			2. We found b3-b4 fringes using retro at 7.09mm (with retros in mirc-alignment positions from last night).
			3. gdt estimator (with no accumulation) seems to perform reasonably well, although true test is with accumulator.
			4. ep found interesting issue with cache that might be using up the free memory on mirkwood
			5. we continue to have intermittant problem with mirkwood where it won't boot after switching from new to old mirkwood drives. the chassis may be wearing out or something else?
			6. hopefully tomorrow we will ahve lab fringes in b1-b2, b3-b4 early. we will test the gdt acuumulation , will get new fringe data to optimize opd map, and will test state matchine using delaylines. if we get this done we can go on sky.
