Where:
XT – actually measured values,
Y – determined (unknown) properties of the object,
P – matrix of calibration coefficients,
E – matrix of errors.

Feature of PARCEL softwareFeature of PARCEL software
The feature of the PARCEL software:
program is adapted under the routine analysis: options to to simplify the operator's work
3 ways to create the calibration model:
1. Enter specific model parameters (manual selection)
2. Optimization module (step-type optimization of parameters)
3. Optimization template (saved settings for each step)
