sd.fitter.store_fit - Function
5.1.4 Save fit parameters
Description
Save the fit parameters.
If filename is specified, the method saves the result in an ASCII file. Otherwise, the result will be stored in the scantable. More specifically, the result will be stored in FIT subtable in the scantable.
It works both for spectral line fitting (gaussian or lorentzian fitting) and polynomial fitting although it is not sure if the latter is useful or not.

filename |
| If specified, save as an ASCII table

| allowed: | string |
|
| Default: | None (store result in the scantable) |

Example
s=sd.scantable(’OrionS_rawACSmod_cal’,average=False)
f.set_scan(s)
# set fit function as gaussian
f.set_function(gauss=1)
# set gaussian parameter with centre fixed
f.set_gauss_parameters(peak=0.5,centre=4100,fwhm=200,centrefixed=1)
f.fit()
# store fit in the scantable
f.store_fit()
# store fit in an ASCII file
f.store_fit(filename=’fitresult.txt’)
