Next: Optimization of spectroscopic observations Up: On the problem of Previous: On the problem of . In comparison with spectroscopy of extended extragalactic objects, the task of observing stars with a high spectral resolution is traditionally given lower priority. ... A ``natural'' response of some researchers of stars and starlike objects is preferential use of low and moderate spectral resolution techniques, where one succeeds in minimizing losses at the spectrograph input. ...

. The Guest FTP Service at the University of London Computer Centre provides a gateway service between InterNet file transfer protocol (FTP), and the file transfer mechanism used over JANET (Blue Book NIFTP). Suppose you can only transfer files between your local host and other remote hosts on JANET using the hhcp command. This service enables you to transfer files to and from hosts on the InterNet through its gateway.
