This center must have been obtained before. This will give you the Summation center , as well as the Spatial summation radius , which should be large enough to enclose ALL the star energy. Polynomial smoothing may be used on the correction curve, with a given Degree . They can be recalled at will, and are used each time the Compute throughput window is opened. Each spectrum in the object datacube to be flux-calibrated is multiplied by the flux correction spectrum obtained during the preceding step.
Care is taken of the different integration times and air masses.
You can type it in directly, or use the browse icon at the end of the field, or drag and drop it from the Reduction folder . Same input possibilities as above. This will be the end product of the reduction process for this exposure. Back to top of chapter.
