This week the image of a point source (so-called PSF) has been determined over the full CHEOPS field of view. The telescope is defocussed on purpose to spread the light of one star over many pixels. The image consists of many measurements taken at one single wavelength in the optical spectrum (at 650 nm). All [...]
First flat field images have been taken during CHEOPS calibration campaign. This flat filed has been taken at the wavelength of 400nm.
The bench cover installation has been completed with UGE. This was the last step before starting the CHEOPS calibration activities.

The CHEOPS telescope has passed the final acceptance vibration. The team performing the vibration test proudly standing in front of the telescope which is still mounted on the shaker. It is protected from contamination by bagging and a clean tent.
