Star at 8:00pm

Check the trigger in the UTH, the fiber is changed by the spare and the check test is good. The spare fiber is left connected. Original fiber is checked and it is seems working, this fiber is keep it.

Flattening half resolution

Check of the 500x500 int mat acquire and redux yesterday.

Noise measurement

Taking a few burst we can see some convection with a different pattern than yesterday, this could be cause by the High bay hatch that is completely open.Measurements of the noise is taken; 1000 measurements

file: 20130827_041100_noise

The telescope crew started to close the hatch.

Hexalign calibration.

@9:00pm The hexapod started a new calibration. AdOpt >print,hexapod_opt_calib(ave=5)

hexapod position:

x	y	z	Rx	Ry	Rz
-0.19	0.93	4.18	-166	-144	0

Actuator Mapping

IDL> a='/towerdata/meas/adsec_calib/if_functions/newmodes_20130826/MMmatrix.sav'
IDL> make_offload_matrix_proj,a, /ver

then, the index of pixel corresponding to each capsens may be obtained with: q = draw_act_map(reference_mask, act)

FF-MATRIX TUNNING

Command used; print,collect_ff_data(/no)

The script to run the collection of the data didn't work. When the routine rested the shell and the load program, the start up process didn't complete correctly. It is seems that some files; corrupted the startup of the mirror.

@6:00 am the problem is solved and the acquisiton of the FF-Matrix is started

act#279 is showing a spike like residual in the data. to be excluded

IF modes collection for the KL basis

i4d_opt_intmat(600,660,avera=11,FORCE_sc=0.5/0.3)

print, i4d_opt_intmat(i*25,i*25+24, ave=25)
