More specifically, vsnet-recent-wanted will bring you daily requests of observations of many CVs ;-). > Similarly, you could show > long-period variables not observed in the past x.x fraction of phase, > weighted so you'd get more observations near minimum (say), or other > parameters. In LPVs, this approach is not extremely practical, since the number of objects is very large, and one must know which phases were observed by the observer before using such service. This requirement is usually beyond human memory; in other words, a traditional strategy spreadsheet (or vsnet-miracirc) can equally serve visual observers. > Under the smart scheme you probably would because the person who > seeks only SS Cyg likely doesn't have the wherewithal to observe V1668 Cyg, > so "tonight" that guy/gal doesn't care about V1668 Cyg. I simply showed a location-oriented plot (of recent observations) may not be very practical (assuming that SS Cyg and V1668 Cyg are located within 1 degree). The same would be true for V630 Cyg and V632 Cyg. There is no guranteee that V632 Cyg was observed when there was an observation of V630 Cyg. For individual visual observations of CVs, object-oriented service is more practical than location-oriented one. > Just about everything any of us does is more superficial than > could be inferred from words we write about them. B-) Everyone should remember this :-) Regards, Taichi Kato
