Thank you Chris for responding.

I certainly agree on the two distinct processes of reduction.

One of the Articles on ablation modes I was reading was under a search of 
Bolide emission is titled  "Radiation Study of Two Very Bright Terrestrial 
Bolides...."

The URL is too long but it is an Icarus Abstract, Volume 121, Issue 2, June 
1996 pages 484 to 510.

Incidently, I believe we agree that camera and substrate characterization is 
an intensity variable along with meteor physical size, surface area of 
photographic capturing(apparent nearness) of a luminous object are just some 
of the variables which can show a Sun bright object as a less luminious 
object, and wall-to-wall saturation is not a good estimator of Sun Bright 
either.
