A case of plagiarism
The wavelength calibration of the tunable filters of the instruments OSIRIS at GTC was uncertain when it saw first light. The equation provided in the manual was insuficcient for our needs, and we had to work out our own calibration, which was published in a PASP paper in 2011. This paper was descredited by the OSIRIS scientific team with that arguments that ''they are based on completely erroneous optical concepts'' and ''their formulae depart from the full correct calibration''; see the image captured from the webblog of the team,
However, they copy the optical model and the equations we derive in our paper without citing us in their MNRAS paper on the OSIRIS calibration publised in 2014. This is an image captured from their paper,
which I include to show that their equations (10) and (11) are identical to our equations (6) and (5),
