You should not stop. You have just made the same unsupported assertion that you made in the electric universe thread. You did not read or reply to my question then:
Maybe you will answer now.
Sorry. I did not see your reply to this post previously.
Let me preface this with the caveat that "optical tables are known to be inaccurate to experimentalists at moderate to extreme ranges due to the lack of experimental data.
Theorists do not incorporate this caveat when using these and other table for astronomical (and other) purposes. I seen many papers written using these tables with no experimental data."
Told to me by Bill a experimental hardcore scientist. I need to find him and talk to him again about this.
So for TOPS;
The parameters that I entered are as follows;
Density- 10-7 g/cm3
Energy- 6000k @ 11,000K per eV = ~.6eV
Composition from Wiki.
"The surface of the Sun consists of hydrogen (about 74% of its mass, or 92% of its volume), helium (about 24% of mass, 7% of volume), and trace quantities of other elements, including iron, nickel, oxygen, silicon, sulfur, magnesium, carbon, neon, calcium, and chromium."
I stuck with a H-He mixture. I also tried Neon and other gases
Pretty straight forward..
I fiddled with the Photon energy group bounds (in keV) to get the range that I was interested in.
I then selected Frequency dependent opacities because that gives you specific frequencies along the x axis with amplitude along the y.
Then selects the output style format. 2-D Plots of frequency dependent opacities.
Then you go to select Data Output Options. Select PS(postscript) output.
The GIF output format does not seem to work for me in Firefox 3.5 so I use Ghostscript to view the final output.
Why??
I was required to plot plasma opacities in connection with work that I do. I am a lab tech working with Dr Felipe Gaitan, the discover of Single Bubble Sonoluminescence. I have a couple of patents and a (the last)author on a paper due out in a couple of months in The Journal of the Acoustical Society of America.

My opinion in no way reflects the opinions of my employers.
My opinion is simply an exploration into alternate ways of interpreting visual data gathering techniques..
Here is a good article in Nature on Sonoluminescence work done at UIUC.
Plasma formation and temperature measurement during single bubble cavitation

Can you tell us this so that we can tell whether you are lying or not:
- What parameters you put into the TOPS page to get your results?
- How much is "large"?
- When you plug "large" into the optical depth equations is the result 4800 kilometers? Or even 500 kilometers?
Large is a 75% increase in "optical depth" as compared to the frequency 200 nm away...
I did not actually compute the optical depth with the new numbers.
this also depends on the brightness of the source. The source is loop foot prints at 1 million degrees lighting up the surrounding area.
Do you think the when we look at the loop footprints we are looking under the photosphere?
It doesnt matter what the optical depth is if you can see the surface.
If think the sun is a plasma ball then you will not see the surface.
You will say there is solar moss in the chromosphere, and it still doesnt matter because you are not able to look out from the inside to verify...
And another question:
Why do you think that all astronomers for many decades have been deluded into thinking that they cannot see into the photosphere just by applying a filter to their telescope?
Because of the way they think the sun is constructed. Nobody thinks they are looking at a solid surface.
Here is the blackbody emission surface of the sun at viewed at 171A through the photosphere.

From the JET website.
"The Science of JET", by John Wesson".
"The initial idea was that of detecting the blackbody radiation from the thermal plasma ions. However, when the ICE spectra were measured they were not consistent with this expectation, having instead narrow equally-spaced emission lines, the spacing being proportional to the magnetic field, and intensities much larger than the blackbody level. The spectrum from a deuterium-tritium plasma is shown in Figure 13.4 (below). The observed frequencies depend on the magnitude of the magnetic field at the location of the emission and, surprisingly, it was found that in JET this meant that the emission comes from the edge of the plasma in the outer midplane."
People learn new things all the time.
As I have said I have never seen a single experimental example of a thin or medium thin plasma produce a blackbody.
Only in astronomy does this idea exist.
