The following spectra were obtained between 1997 and 1999; they are all flux calibrated and generally span the wavelength range 6000-10,000 A. Spectral types are on the Kirkpatrick et al system as defined in Kirkpatrick et al ApJS, 77, 417 (1991 - for M dwarfs) and Kirkpatrick et al ApJ 519, 802 (1999 - L dwarfs). While not all of these stars are primary spectral standards, they are all bright and should provide an adequate reference sequence. ... LHS 320 ,sdM2, red spectrum . ...

. Unix considers any device attached to the system to be a file. And that includes your terminal! . By default, a command treats your terminal as the standard input file from which to read in information. Your terminal is also treated as the standard output file to which information is sent from the command. This action can be changed by redirecting standard input and standard output from and to any other file. Redirecting standard input . Redirecting standard output .
