Response for the U,g',r',i',Z WFC filters. The dashed line shows the EEV CCD response, the dotted lines the filter responses and the solid line the overall filter response.
For a visual comparison between the current standard INT WFC filters and the SDSS set click here . For more details on filter reponses see ING filter database.
The overall QE of the recommended U ,g',r',i',Z filter set convolved with the EEV CCD response is available as a postscript file here . The Harris and RGO filter set B, V, R, I response is available here and the Kitt Peak B filter response is available here .
The EEV 42-80 QE is also available as a separate table.
The filter specifications for passbands used in the WFS are itemised below for convenience.
