Re: [APML] Table of emission lines-a bit more

["bert katzung" <katzung1@home.com>]

Hi List:
Relative to a couple of things regarding the emission line data:
I checked AMOACP and Figure 7.5 shows the lines and their intensities for
the Trapezium. The He[1] line at 5876 is about 10% as high as the Halpha
line. Not sure whether that qualifies as "major" or not but I'll try to add
some quantitation of each of the lines to the table. Kaler's book has a
spectrum (intensity of lines not quantitated) for a planetary nebula in
Puppis (NGC2440) showing a moderate signal at 5876 (figure 11-4).

Jack Marling's chapter in AMOACP shows the same Trapezium figure and also
shows a distribution of the sodium and mercury light pollution lines. I will
be adding these lines to the table on the website.
