RAMP_BasicLinFit, data0, fit_params
Basic linear fit, returns intercept and slope for each pixel
Parameters
- data0 in required type=fltarr(2048,2048,Ngroup)
ramp datacube to be fit
- fit_params out required type=fltarr(2048,2048,2)
intercept => [2048,2048,0] slope => [2048,2048,1] sigma_intercept => [2048,2048,2] sigma_slope => [2048,2048,3]
Examples
