This study is presented as a composite and as such it is constructed to be shown as it was developed, as it happened.  New on this study was the measurement of temperature which is not on the first bits of data but is on the original and will be mentioned with each segment. At he end of the series there is a total data table with the temperature readings.

The Velador was stationary, bolted with clamps to a solid desk in my basement. The basement has less environmental variations and the door to the furnace was closed isolating the area.  At points where the laser image was migrating off the LCD a shot was taken and the laser adjusted as quickly as possible to the LCD center and another shot was taken.  This allowed me a large graph surface to use with the relatively small LCD size. Basically an unlimited LCD area to use. At one point when a second velador was carefully brought close to the master Velador in typical real life style the master was bumped and had to be readjusted. This is indicated as we go thru the data. The initial 6 runs were sequential shots on each day and at this point i was trying to find a sequence of the data from day to day. However a pattern was not apparent and fortuitously i saw on a different scale a movement of the family of day spots, dropping on the LCD so i decided to abandon the family type spots and just record the daily movement of one shot. this was an aid to the camera as it is having serious start up problems--cause unknown.

The images are “hand” analyzed.  Previous work had shown there is no real difference in spot position using the self timer verses just pressing the shutter. There is a delay in recording the shot and the image is taken it seems after the pressing of the shutter vibration is over. So the images are from just pressing the shutter by hand.

 

The orientation of the Velador was laser at the 60 degree position and the camera at 240 degrees  (Laser 60 deg to east of north--camera 60 degrees west of south.) The Velador was 2 meters below the ground level.  It was on a level surface and solid to a heavy desk.   To view the horizon from the Velador perspective one would have to tip one end up about 10 degrees--however it was level when being used.

 

The first column is the time of that day. The second is X and the third is Y value. The Temperature was 53.6 F.
There is a complete set of all data points with temperatures at the end of this presentation.
