| Description | |
| Data for the upwinded and centred polynomial fit interpolation schemes. | |
| The linearCorrection_ determines whether the fit is for a corrected | |
| linear scheme (first two coefficients are corrections for owner and | |
| neighbour) or a pure upwind scheme (first coefficient is correction for | |
| owner; weight on face taken as 1). | |
