parmGLOptimLRCBounds: parmGLOptimLRCBounds

In REddyProc: Data processing and plotting utilities of (half-)hourly eddy-covariance measurements

Description

Optimize parameters of light response curve and refit with some fixed parameters if fitted parameters are outside bounds

Usage

parmGLOptimLRCBounds(theta0, parameterPrior, ..., lastGoodParameters.V.n)

Arguments

theta0	initial parameter estimate
parameterPrior	prior estimate of model parameters
...	further parameters to .optimLRC, such as dsDay, and ctrl
lastGoodParameters.V.n	parameters vector of last successful fit

Details

If parameters alpha or k are outside bounds (Table A1 in Lasslop 2010), refit with some parameters fixed to values from fit of previous window.

No parameters are reported if alpha<0 or Rb < 0 or beta0 < 0 or beta0 > 250

No parameters are reported if beta0 > 4*initialEstimate, to avoid cases where data is far away from saturation.

Value

list result of optimization as of .optimLRC with entries

theta	numeric parameter vector that includes the fixed components
iOpt	integer vector of indices of the vector that have been optimized
