Temperature variations and n+/o+ in the orion nebula II the collision strengths

We continue an investigation of electron temperature (Te), mean{square Tevariation (t2), and the N+/O+ abundance ratio. Our previous analysis of HSTspectra of the Orion Nebula used collision strengths for N+ by Sta ord et al. (1994).Here we examine the consequences of changing just these collision s...
