[time-nuts] Gamma-ray and jitter

I had already been reluctant prior to give the link to my curve 
(risk of Off-Topicness), but eventually thought that the curve 
could be an useful reference.

Please allow me to conclude, clarifying some points that have 
been asked or commented on. This could help you to decide whether 
or not to keep into account this curve for your own speculations 
regarding the general issue of jitters.

>>as the hemisphere shifts over the sky over the years due to the 
angle of the earth.

The hemisphere shifts, but its orientation toward fixed stars is 
substantially constant (there is only the very negligible parallax 
error). Not the same thing toward the sun.

>>in the Northern Hemisphere, you see the galactic center during 

Given the above, I see the galactic center every day in the year, 
sometimes during daylight, sometimes (six months later) during 
night. The time at which the galactic center transits over my 
meridian shifts over 24 "solar" hours in a year. If I consider 
Local Sidereal Time, the galactic center transits over my meridian 
always at the same LST hour (Right Ascension), namely around 18. 
This is true all over the word, that is the galactic center 
transits over any meridian always at 18 LST of that meridian.
(note: 18h LST might mean any solar hour in the solar day, 
depending on where you are in the year).

Seasonal effects do exist in my data, as shown by the different 
levels of the 8 curves on the left. They are lost in the top-right 
two-year curve, which averages the 8 "quarterly" curves.

These curves do not carry the temperature info, but only the RMS 
noise info.

About the scales and time-references:

Y values are the RMS noise, expressed in deg C, times 10. Divide 
them by ten for the actual values.

Each curve is 86160 seconds long (not 86164, the last 4 seconds 
being lost for convenience), and is carefully aligned to the 00:00:00 
Local Sidereal Time for my location.

The two-year curve is the average of 736 sidereal days, the quarterly 
curves 92 days each.

Years of the test: April 2002 to April 2004.

The previously mentioned NASA article states that the structure 
(gamma-ray bubbles) spans between the constellations of Virgo and Grus. 
This means between RA13h and RA22h. You could see yourself what part 
of my graph (in the two-year curve) is involved.
