Stage III (Science Detector NIR)
The goals of this stage was:

In this stage we had the finally configuration of the instruments and using the science final detector. In the first sub-stage we use the pinholes mask in the focal plane and the CSU in the second sub-stage (for first time).
The results, can be summarised as follows:
- The optimization of the readout modes.
- Optimization of the reduction data packages (DRP).
- Optimization of the DTU and flexure corrections.
- Geometrical distortions in the FOV.
- Linearity, saturation and gain tests.
- Dark current and readout noise.
- Stability and precision of the CSU.
- Quality of the flat-fields and focus in all bands.
- Spectral calibration.
