Abstract:    Page 31: The easiest way to see this is by comparing the 2-D intensity contour plots of Figures 19 and 21. We are immediately struck by the fact that the locations of brightest intensity in the 304 Å and 335 Å lines are reversed! This is exactly opposite what we would expect if p-r were the dominant line formation mechanism for the 304 Å line. Also, the relative areas of intense radiation in the two lines are reversed, again opposite what we would expect under p-r conditions. And these results apply primarily to active region intensities, where p-r is more likely to have a significant effect; in the quiet Sun, its effect is even less. This is strong support for the electron collisional excitation formation of the 304Å line over most of the solar atmosphere.
