Wanted: well-observed southern Miras or other variables

Hi,I'd like to query the observers among us to see if anyone can quickly recommend one or more Mira or other variable stars that match thefollowing criteria: - southern, so it has good ASAS coverage - fits well within the good quality ASAS range (perhaps V=8.5 to 13) - has an excellent visual sequence, and has had for a long time - is very well observed visually, and - isn't too red (i.e. not a carbon star).What I'm looking for are stars with lots of visual data that can becompared with ASAS (or another photometric data set with reasonablywell-defined bandpass). It will be a bit tedious to go through all ofthe AAVSO/RASNZ lightcurves and compare them to ASAS, so if anyoneknows any good ones off the top of their heads, please post a reply.The reason I'm asking is the following: the brute-force (and naive) way ofmaking presentable visual light curves is to do a straight averaging of all visual data without regard to how many (or which) observers happento be observing; we just create 10-day averages or 7-day averages or whatever. I'm playing with a few ideas to see whetherthere are more statistically rigorous ways of creating mean lightcurves. One obvious way is to go observer-by-observer and compare eachone to disentangle physiological and perceptive differences betweenthem. Another is to make sure that each averaged point has a sufficientnumber of observers in it to yield a meaningful statistical measure of the uncertainty.And I'd also like to study individuals who contributed to the light curveand see how their data changes over time, whether their data gets better(more experience) or worse (degraded vision) over time.If anyone can suggest good visual light curves to look at please do.
