Description: Deadband for noise rejection of measurements
in MHE

Used in estimation problems with APM.EV_TYPE=1 (l1-norm objective). The measurement gap (MEAS_GAP) defines a dead-band region around the measurement. If the model prediction is within that dead-band, there is no objective function penalty. Outside of that region, there is a linear penalty specified with the WMEAS parameter. The WMODEL parameter is the weighting given to deviation from the prior model prediction but does not have a deadband around the prior model prediction. The gap is only around the measured values.
