Scaling Catalyst Raw Data Values

Can I scale Catalyst raw data values?

Yes, raw channel values can be scaled as needed.

You can scale values by gain and offset, or by using the two-point scaling method.

  • With gain and offset, the reported value = ( gain * raw value) + offset.
  • With two-point scaling, it is necessary to define two separate points, or cordinate pairs.
  • With this linear relationship, any point may be calculated from the formula Y = Mx + b (where M is the gain and b is the zero crossing point).
  • The gain may be calculated from M = (y2-y1)/(x2-x1), where x1,y1 is one coordinate pair on the graph and x2,y2 is the other
