A few additional highlighs
Hi everybody, my name is Fernando Marziali, I'm the originator of the
request for time exchange posted by Mike.
Thank you Mike for postin and thank you all for comments.
My feeling is that I was not completely clear as to the scopes of the operation.
If I can improve the picture, it will be easy for you to find observers
in the same range of interest and pinpoint candidates to the exchange.
The best way to cast light on the whole thing is describing the usual job
we do every clear night.
The 16 inch (not 16'..) RC shoots a number of symbiotics, say 5 to 10, in
the Johnson&Cousin filters (UBVRI band), 5 to 10 times. So 25 to 50
quadruplets are generated, for a total 100 to 200 Mb. A professional
Photometry Software stacks and calibrates and performs local to std
conversion for the single quadruplets. Last step: data reduction and
sending the complete package to AAVSO. The final result is a dot in a
magnitude plot for every quadruplet. The dots of a single star build up
the star light curve for that night.
The ovarall error of the scope+software chain is about 4 thousands of
magnitude (in our highly polluted sky), well below the 1/100 mag
necessary to unambiguously detect outbursts outset and details.
By the same technique we can follow extrasolar planets eclipsing their
mother star.
Many stars we are taking care of, are low or negative delta. This severely
limits the hours we can follow them and impacts badly on precision and
consistency, due to thick layers of atmosphere.These same stars are
high above on your sky during our daylight. This is the advantage for us,
and symmetrically the same advantage is for your observers-obviously on different stars.
Another symmetrical advantage:
both OMB and Australian observers could exten research to opposite emisphere stars.
From all above it appears that our proposal can be of no interest to photographers, of high interest to Variabilists
Thanks for you patience - Fernando - OMB Osservatorio Monte Baldo
