Model Grid¶
Fit a line based on parameters output from a grid of models
Module API¶

pyspeckit.spectrum.models.modelgrid.
gaussian_line
(xax, maxamp, tau, offset, width)[source] [github] [bitbucket]¶ A Gaussian line function in which the

line_model_2par
(xax, center, width, gridval1, gridval2, griddim1, griddim2, maxampgrid, taugrid, linefunction=<function gaussian_line>)[source] [github] [bitbucket]¶ Returns the spectral line that matches the given x-axis
xax, center, width must be in the same units!

line_params_2D
(gridval1, gridval2, griddim1, griddim2, valuegrid)[source] [github] [bitbucket]¶ Given a 2D grid of modeled line values - the amplitude, e.g. excitation temperature, and the optical depth, tau - return the model spectrum
griddims contains the names of the axes and their values… it should have the same number of entries as gridpars
