To view an image or to work with data, you must be in the directory containing the data or specify the location of the data exactly (the pathname).
For example: Your directory might be /home/smith/ . At SAO, the ROSAT data for observation rp123456 will be in /data/rdata/godata/rp123456/ . The PROS package contains sample ROSAT and Einstein data which are in the directory /pros/xray/data which is loaded with the IRAF task ``xray''. To avoid typing long directory names within IRAF we have assigned ``logical variables'' which are recognized as aliases for the full directory name: ``xdata$'' for the directory with sample data.
Thus within an arbitrary working directory and within the IRAF environment, to look at an image the command is,
tv> display "xdata$rp110590_im2" 1If Einstein data are loaded at SAO they will appear in the directory /pool14/i1234/ . To view the data from Einstein IPC sequence 1234, type
tv> display /pool14/i1234/i1234.qp 1
