Note: current daily procedure is as follows:
      - choose samples for days measurements
      - determine robot calibration parameters using spot 
        photometer and positions alpha=0, beta=0, alpha=0, 
        beta=78.75, alpha = 70, beta = 0 with grid on sample.
        p and l parameters are adjusted until the center spot
        (as determined by the center of the middle row on the 
         grid) remains the same. There is a systematic error
         that the spot moves to the left of the center as the
         robot moves to alpha = 70, beta = 0. In addition
         the position changes slightly when the robot is 
         put to alpha = 70, beta = 0 and then back to alpha = 0
         beta = 0.
       - for each sample, set aperture and if necessary set the
         video settings and then begin calibration followed by 
         measurements. The aperture is set by using the bmpinfo 
         program on pictures taken from the darkest and 
         brightest positions (at times the brightest position
         is difficult to find because of specularities and 
         variation of surface normal)
         Note the bmpinfo program was first used for sample 5, 
         measurements before that may have overflow/underflow 
         that was not detected.

Beginning sample 9 frosted glass.

Using new procedure for for setting white balance, i.e.
the bmpinfo program with the standard card (with gray strips)
to make sure that the pixel values for the gray strips
are approximately equal.

The rgain and bgain of the video camera was adjusted to
rgain -10 , bgain -50



didnot finish sample 9 with this lamp, after aperture setting 
decided
to wait for new lamp which Hans is moutning. Will do 
robot calibration for each sample now.


12:00 noon finished finding robot parameters for two more 
samples,  switching to new lamp now

white balance for new lamp: b -23, r -23
voltage at 11.00 V
setting aperture at two ticks above 11
p = 17, l=167

1:03pm starting measurements

did calibration afterwards. integration time at 5 seconds

there is no frame on the lamp. we'll put one on now.
we do a full standard calibration now.

3:31 finished full calibration
2:55 finished
