Hi All, Stupid question time?
https://www.lightningmaps.org/blitzortun...her_graphs
Looking at the signals on this page there is obviously a lot of variability in signals even for the same stroke. If you look at the stations chosen for location nine of them are greens, six are reds, and five are blues. Some of the signals seem vastly over-driven, being cropped flat topped and distorted, some with various amounts of noise and some that are barely recognisable as lightning at all?
After looking at several pages like this I came to the conclusion that the criteria for being chosen for the location of strokes has nothing to do with quality of signals, but is just based on the first to arrive at the server. Greens send less information, so they predominate. Blues with H.O. or E.O. Send less info but more than greens or reds so they bring up the rear. there are very few 3 or 4 channel blues represented in this lottery?
Yes, this is all just for one stroke! I have not edited it in any way. The chosen stations are underlined.
My question involves the timing in micro seconds at the top of each graph at a quick scan this varies from a few + microseconds up to several + hundred microseconds, the average being +50-+60 microseconds! Only the fastest are chosen!
Does this timing have anything to do with the decision about whether your signal is chosen for the location calculations? Based on my short observation it seem to.
Secondary question. Is there anything that an individual station could improve on this time delay? Reduce channels and get a better result in the lists
Are there things that we should avoid doing that might increase this delay? Send good quality signals on all channels?
Last question, at least for the moment. Is this timing of great importance or is it the time that has the seconds to nine decimal places that is the important time?
I wish I had studied statistics more when I was young, and I wish there was a quicker way to get all this data from the archives.
Regards,
Brian.
