3. Compare the current scan rate (Speed) to the requested rate. The Speed (Figure 8) of the camera will be in the first box. If the values need to be changed to match the requested values by the science party, please proceed to the calibration section below as you will need to do a full calibration. If the values match, close the ‘Image Scan Setup’ window and proceed with the following checks. Speed of 8 to 10 is the most common value and must be less than the scan speed value calculated in the JAI Camera Setup utility.

- Stripe Width: Centered in the middle of the core, this determines the width across the core that will be used to calculate RGB data. This is typically set to 2cm. While the value can be changed higher or lower it is commonly at 2 cm. The advantage is this width provides enough material to not exaggerate small disturbances but rather provides RGB data representative of the bulk lithology.
- Decimate Interval: The interval that sets the recorded offset along the length of the core. This value can be set between 1 - 2.9 cm
- Mean or Midpoint: Can choose how RGB is calculated for the interval. Interval mean calculates the mean RGB values over the interval. Interval Midpoint uses the RGB value at the center of the interval. This is typically set to Interval Mean.
