The EMIR Data Reduction Pipeline is being developed using the GTC Developement Kit.
The figure below Figure 1. shows the steps in the reduction process. In the infrared range, the sky substraction is crucial. This is shown in Figure 2..

Figure 2. Evolution of the reduced image (left) and the objects mask (right) with the iterative steps of reduction. The quality of the reduced image increases as more objects are included in the mask. One step is not enough to obtain results with good quality.
