Einstein FITS files can be read into PROS using the standard IRAF and PROS routines, dataio.rfits for images and xray.xdataio.efits2qp for Event Lists. The user is prompted for the name of the FITS file and the dataset is drawn from (IPC Unscreened Data, HRI Event lists etc.) For example;
xl> efits2qp input FITS file name: i2029n40.xpc dataset (hrievt|ipcevt|slew|ipcu): ipcevt output IRAF/PROS QPOE file name (.): test Writing output QPOE file: test.qp aux=.convtgr, type=convtgr -> test.qp
