hi jeff - last night i was thinking (since even i was
able to run your DB example code) that today i'd be able to click
around the CVS browser and figure what what other DB tables
i could load so that i could tabulate e.g. start/stop times,
and nos. of events along w/ the polarity vs day number...
(and so on)...

gosh was that naive!

- i found two web DB browsers, one required a password (none
of my guesses worked) and the other only listed the MagFactor
table.
- i found another example code of yours (ReadConfig.cc) under
CVS and i thought that showed how to list all available tables,
but somehow that didn't work...

so, can you point me at a way i can learn what tables can be
accessed? or other examples? or who i should bug if your
too busy for this?

thanks again for all your help
