Bemerkungen:
1) Die quadratischen Elemente von Wunder sind für X Ari und
XZ Cyg immer noch
gültig.
2) Basieren auf von Wilhelm Kleikamp gewonnen Zeiten maximaler
Helligkeit
auf Sonneberger Platten:
2446592,487
2446909,508
2446941,479 2447263,524
2447672,476
2447717,465
2447805,278 2448746,482
2448769,490 2448833,416
3) Elemente zu UX Tri sind provisorisch. Zwei
lichtelektrische Maxima von den
Herren Husar und Achternberg weichen stark
von visuellen und photografischen
Zeiten maximaler Helligkeit ab.
