The Suprime-Cam filter system

This page describes the Suprime-Cam filters, and the transformations between the Pan-STARRS photometric system and Suprime-Cam.

The transformations were done using (g-i)Pan-STARRS as the reference colour. The Pan-STARRS filter nearest the centre wavelength of the filter was used as the reference magnitude. The transformation was expressed as a 3rd order polynomial with x being g-i, and y being the difference between the Suprime-Cam magnitude and the reference Pan-STARRS magnitude.

The Transmission Function links point to text versions of each filter. These represent the full response of the system, including the atmosphere, the primary mirror, the Suprime-Cam optics, the filter itself and the CCDs.

In the plots below, the left panel shows the filter curves, together with the relevant Pan-STARRS filter. The black and red curves show the Pan-STARRS g and i filters. The green curve shows the reference filter. The right panel shows the transformation itself. The green and blue dots show the Pickles and CALSPEC/a> stars. The magenta curve shows the fit, also indicated in polynomial form. The vertical lines show the colour range where this transformation is valid.
