The Isaac Newton Telescope
IPHAS was carried out using the 2.5-m Isaac Newton Telescope (INT) on the Observatorio del Roque de Los Muchachos, La Palma in the Canary Islands, Spain. Full details are available at the ING web site - see www.ing.iac.es
The Wide Field Camera
The IPHAS survey is using the Wide Field Camera (WFC) on the INT. Details are available on the ING WFC pages and on the CASU WFS pages.
The transmission profiles of the Hα, Sloan r' and i' filters used in all IPHAS observations are plotted below. The r' and i' filter profiles are plotted as solid lines, whilst the Hα
profile is shown dashed. The dotted line is the mean WFC CCD response
at the cooled working temperature. These profiles are available in
numerical form from the INT/WFC web page.
