Hi,

I have a set of observed data of flux vs wavelength.I am trying MPFIT to fit a voigt function. I defined the function as

FUNCTION fit,p,X=x2,Y=nflux2

model=double((voigt(p[0],p[1])*1e-13)/(p[3]*sqrt(!pi)))
return,(Y-model)/err

END

But when I run this, the following errors are coming

FUNCTION fit,x2=X,nflux2=Y,p
^
% Programs can't be compiled from single statement mode.

return,(Y-model)/1
^
% Syntax error.

Why is this happening?
