    wavelength = [412,442,488,530,554,645,747,857,1242]
    for s =0,ns-1 do begin;ns
    for l=0,nl-1 do begin;nl
    Y=data[s,l,*]
    coeffs = powerlaw_fit(wavelength, Y)
    endfor
    endfor

    is there any method to improve efficiency？thanks

    I have to do something similar in my work -- several million independent power-law fits. I use the IDL_IDL bridge on my multiple CPU machine to let me run many fits simultaneously. See http://www.harrisgeospati...he__thread_pool.html
