Comparing UCVM's CVM-S4.26(cvms5) with a set of ascii model files (CVM4SI26_model) from enjui's directory on intensity(enjuilee/work). The ascii model file's grid points match Billy's grid points and hence it is reasonable to assume that the latlons from the ascii model files can be use to query against UCVM's CVM-S4.26.

Billy's VS and VP are result of averaging neighboring gridpoints (25 grid points to both sides of the target grid point = 2601 total grids points including the target grid point)

Extraction steps:

Retrieve target latlons from Billy's target list Calculate grid points used to calculate the average Use grid points to extract VS/VP and latlons from the ascii model files Create model VS csv, model VP csv output files Collect up a list of latlons and use them to extract VS/VP from UCVM Create UCVM VS csv, UCVM VP csv output files

In addition, a set of VS and VP output files are made with target latlons without averaging with its neighboring latlons

Data points are calculated with 2 sets of data points from comparing profile plots

Closeness equation used with VStarget and VSbase,

              abs(VStarget - VSbase)
