**Parameters:**-
*-in*Input datacube (of an observed flux standard star) *-out*Output flux standard spectrum *-col*Lens position columns (defaulted to A,D) *-center*Position of the flux standard star *-radius*Radius of the summation region around the flux standard star *-psf*PSF sigma1,sigma2,ratio (using a PSF estimate to correct for incompleteness)

**Returns:**- Error status

**Note:**- This program originated from the split of the original
`comp_flux`

(up to v1.13) in two distinct components:- extract_flux: extract the flux standard spectrum from the cube
- calib_flux: compute the flux correction from the flux standard spectrum and its reference table.

- crude aperture photometry (nothing like an optimal summation or PSF-photometry)
- it does not take into account the differential atmospheric refraction.
