Appendix 1: Initialization File Settings
This appendix tells the use of all of the settings in the Initialization (INI) file. You may never have to change any of these settings, but it is good to have an idea of what they do while the software is operating.

A. The [raster] Section:
rows: Determines the number of vertical rows in the experiment that the laser is rastered. This should be the same as the columns setting so that the output of the experiment is a square. The combination of rows and columns represents the number of pixels in the scan experiment.
columns: Determines the number of horizontal columns in the experiment that the laser is rastered. This should be the same as the rows setting so that the output of the experiment is a square. The combination of rows and columns represents the number of pixels in the scan experiment.
msperxstep: The number of milliseconds that the X motor is run to raster the laser in one horizontal pixel in a scan experiment. This setting is used to calibrate the raster before any experiments are run.
msperystep: The number of milliseconds that the Y motor is run to raster the laser in one vertical pixel in a scan experiment. This setting is usually set to the same value as the msperxtep setting to keep the scan experiment a square.
msbacklash: The number of milliseconds that the X motor is run after resetting the laser at the beginning of a horizontal row. This is used so that any backlash in the X gears can be accounted for to give the horizontal scans the same starting point. This setting is usually set once during the calibration process.
laserondelay: The number of milliseconds that the application waits after turning on the laser before measuring the photocurrent. This is used to allow the laser to stabilize prior to measuring the data.
laseroffdelay: The number of milliseconds that the application waits after turning off the laser before measuring the dark current. This is used to allow the laser to shut off completely prior to measuring the data. This setting is defaulted to 0 ms and is likely not to need adjusting.

B. The [dataacquisition] Section:
samplestoavg: The number of samples that the application reads from the data acquisition card and averages to create one data point on the scan experiment. This setting can be increased if the scans appear to be noisy.

C. The [paths] Section:
data: The directory relative to the installation path where the data files are to be saved.
