Sample 4 will be rough plastic
     
12:55 setting aperture
      aperture is different than sample 3 
      video settings remain the same
      rgain +5 bgain -15 all setting manual
      
1:00PM imaged the standard sample ccas_04.bmp

1:05PM measured thickness of sample = 1mm
       setting p = 23
       l3 = 167
   
       putting on grid and taking sample calibration images

1:13PM finished getting sample calibration images cca04-0.bmp 
       to cca04-7.bmp
       starting photometer measurements
       first file is data/sample4/124-04.feb
       The last file of the first row is 131-04.feb
        Note: photometer did not need to be adjusted by hand,
              center remained in spot
1:35 PM   second row completer 132-04.frb to 139-04.frb

       
Note: the photometer readings for sample 3 and sample 4 were 
done with 10 second integration time, 1 cycle. All measurements
at 78.75 degrees gave a low signal error but were written anyway


1:43 PM finished sample photometer measurements

1:45 PM starting sample measurements
         
2:00 PM at position 2 put 4 folds of paper
        

        at position 3 sample appeared high
        
2:55 PM finished sample 4 measurements
       (note had to restart texture measurement program
        twice because I forgot to change camera position...
        all parameters p.l. etc were reentered)

2:55 PM going to make tape backup (tape 2a)
