Name

imf_params_cl1 - fit image formation parameters using constrained simplex method

Usage

Input

pw2
a list contains 1D rotationally averaged power spectrum
n1

`n+1`, `n` is The rank of polynomial applied for fitting

Pixel_size

Pixel_size, it can be set an arbitary constant if is not required to give frequencies in1/`Å`.

Output

res[0]
the frequnecies 1/angstrom
res[1]
fitting background or envelope function
res[2]
The original power spectrum for paramters extracting
res[3]

The number of extracted paramters is equal to len(`res[3]`)=`n_1`
