(cba:news) choosing your optical transient...

[Joe Patterson]

Dear CBAers,

I've analyzed all the data so far on ot0747, and ot0845.  The former 
looks to be very well behaved, with a constant period at Psh=0.06073(8) 
d.  Seems to be under control!  I'll send the full lot of data to all 
the observers.

OT0845 is another story.  This now has strong superhumps, but they 
probably *just* emerged, and the star is a bit fainter at 15.  So our 
data on it is very sparse - not enough to really parse the period(s). So 
if you can get comfortably to 15.5 or so, OT0845 is definitely the 
better choice.
