Gets the integer weights used by the zero suppression FIR filter.

<U>Weight definitions:</U>

• Uncalibrated normalized weights are defined as such that when applied to the average pulse with the highest sample normalized to 1, the result is 1.
• Calibrated weights are defined for each crystal, as uncalibrated normalized weights multiplied by an intercalibration constant which is expected to be between 0.6 and 1.4
• FIR weights are defined for each crystal as the closest signed integers to 2**10 times the calibrated weigths. The absolute value of these weights should not be greater than (2**12-1).

If a FIR weights exceeds the (2**12-1) absolute value limit, its absolute value is replaced by (2**12-1).
