Response matrices for the SPI pipeline

last update of this page: 12.3.2007

On this page you find the IRFs and RMFs which can be used for the SPI data. All response matrices have been derived at the EUD at NASA/GSFC. You can either download the IRFs from this page by clicking on the file names (gzipped tar files), or by using the indices of the IRFs in the parameter files (the exact file names which have to be included in e.g. spi_science_analysis.par, spiskymax.par, and spiros.par are given in the table below) in case you work on the GSFC or ISDC system.
