He also showed that the κ = 1/3 scheme (with point-valued solutions) was a third-order finite-difference scheme in Ref.[36], but it is actually true only for linear equations on one-dimensional uniform grids [38]. This κ = 1/3 scheme WebMUSCL stands for Monotone Upstream-centered Schemes for Conservation Laws, and the term was introduced in a seminal paper by Bram van Leer (van Leer, 1979). In this paper he constructed the first high-order, total variation diminishing (TVD) scheme where he obtained second order spatial accuracy.
