... An interactive IRAF task for the analysis of Extreme Ultraviolet Explorer ( EUVE ) emission line spectra is presented. The line flux in extracted spectra may be measured by multiple techniques, including fitting individual lines. ... To aid in identifying lines, the positions of known lines may be marked on the spectrum during the fitting process. Also, model EUVE spectra may be constructed and overlaid using plasma emissivities and source emission measures supplied by the user. ...

... If, while entering a command, you realize that you forgot the full command syntax or want to check something else, a mechanism has been introduced to let you interrupt the command line, execute another command or commands, and then resume with the interrupted line. To interrupt a command line enter ` ' (back--slash) as the last character and hit . The command string is then saved internally. To resume entering the interrupted command line, type ` ' (back--slash) again followed by . ...

... If at any point on such a line we place an ideal compass needle, free to turn in any direction (unlike the usual compass needle, which stays horizontal--such needles exist, see bottom of page) then the needle will always point along the field line (drawing below). ... Because of this attachment, the behavior of electrified gas ("plasma") in space, a gas of free ions and electrons, is dictated by the structure of field lines: Electric currents, for instance, find it easiest to flow along such lines. ...
