Calibration: CAL Integral Non-linearity

ID:  C20  in LAT-MD-00446-04

Description:   This is the look-up table which results from charge injection calibration and provides the conversion from possibly non-linear ADC scale to the linear DAC scale. 

Software required: EGSE

Algorithm:  The calibration input pulse height  is defined in terms of DAC settings. For each DAC setting one provides 1000 charge injection pulses and obtain the average ADC value of the peak of the distribution. The conversion is accomplished by using a look-up table where adjacent points are linearly interpolated.  To be expanded by CAL.
