Multi-Layers estimation of drift coefficients

Description

Multi-Layers estimation of drift coefficients

Usage

mlayer.get.prior(dbin, dbout = NA, model = model.input(), 
                 flag.vel = FALSE, flag.ext = FALSE,
                 irf.rank = 0, match.time = FALSE, colrefd = NA,
                 colreft= NA, colrefb = NA, verbose = FALSE)

Arguments

dbin

The db-class structure containing the 2-D data file. The file must be 2-D and contain one Z-variable corresponding to the sample depth and a locator "Layer".

dbout

The db-class structure containing the 2-D ouput file where the additional variables must be defined and where the results will be stored.

model

The model-class structure containing the Model information. The number of variables defines the number of layers.

flag.vel

Should be TRUE if the estimation must be performed using velocities (the Model should correspond to interval velocities) or FALSE when working with depth (the Model should correspond to interval thickness). If flag.vel is TRUE, the layer time maps should be defined in the grid output file (locator "time" or "f" if match_time is TRUE).

flag.ext

Should be TRUE if External Drift should be used. Then the grid output file should contain the corresponding maps (locator "f").

irf.rank

Rank of the Intrisic Random Function. Should be -1 (for strict stationarity), 0 (for intrinsic) or 1 (for a first order drift).

match.time

When TRUE, the external drift maps and the time maps coincide in the output grid file. They are both defined using the locator "f".

colrefd

Rank of the attribute containing the Reference Depth map. If 0, the reference depth is set to 0

colreft

Rank of the attribute containing the Reference Time map. If 0, the reference time is set to 0.

colrefb

Rank of the attribute containing the Bottom Depth map (if defined).

verbose

Verbose option which recapitulates the main options of the multi-layer estimation.

Value

A list containing:
