Stars for Resolution Testing........Compiled by Robert Argyle

Separations are given in arcseconds for some bright and nearly equal northern pairs. These separations are recently derived through interferometric and speckle data. All pairs listed show little relative motion, so this table should be useful for several years. Hipparcos magnitudes are given except for values within parentheses, which are from the WDS. (2001)

MY NOTES:

note#1Olcott duplicates star ph2 Cancri. According to WDS STF 1223 and phi2 are the same. STF 1223 is omitted from his Field Book list.
note#2measurements given indicates 24 Cancer (STF1224) which is only 1.1° away WDS gives first position angle as 37° which matches figure given by Olcott
note#3Olcott duplicates star STF 1223 in Cancer. According to WDS STF 1223 and phi2 are the same
note#4This pair is labeled OSS 93 on chart #7 of Norton's Star Atlas (6th edition -1937). Webb refers to the pair S 565 as STT 93. Olcott makes reference to Webb's book.
note#5In Norton's Star Atlas (6th edition -1937) it is labeled - H h. 376. In WDS it is labeled Herschel 96
note#6WDS reveals large change in position angle since discovery
note#7From data given by Olcott, STF 2194 is a better fit for this entry. Located just 19' from 83Her. 83 is omitted from his Field Book list.
note#8STF 2007 is in Serpens and not Hercules
note#9In Norton's Star Atlas (6th edition -1937) it is labeled - 23 Her. However it shows it in Corona Boealis. WDS shows it to be - H V 38
note#10WDS shows large change in position angle
note#11WDS shows large change in position angle and separation. Current separation >1", beyond resolution limit of 3 inch telescope
note#12STF 1669 in Corvus and not Virgo. No explanation for difference in posotion angle.
note#13WDS shows large change in position angle.
note#14STF 1919 in Serpens and not Bootes
note#15WDS indicates motion has exeeded 360° since first position angle and separation were reported, therefore both have changed significantly.
note#16STF 1615 in Coma Berenices and not in Canes Venatici
note#1715 CVn is a double, but the WDS first separation is 1.3"- far from 290" Olcott gives. 17 CVn, just 4.6' away, has measurments that better match the data Olcott gives
note#18WDS shows large change in position angle.
note#19This star is marked 212 in Norton's Star Atlas (6th edition - 1939). Using map #12 of that atlas and the WDS, I identified it as H N 28
note#20This star is marked H4783 in Norton's Star Atlas (6th edition - 1939). Using map #12 of that atlas and the WDS, I identified it as South 672
note#21WDS shows large change in position angle.
note#22WDS shows large change in position angle.
note#23This star is marked 236 and is Ophiuchus in Norton's Star Atlas (6th edition - 1939). Using map #12 of that atlas and the WDS, I identified it as SHJ 240
note#24WDS shows large change in position angle.
note#25STF 645 in Taurus and not Auriga
note#26WDS shows large change in position angle.
note#27Wide optical double, not in WDS. The blue 5.5 mag star in field mentioned by Olcott is 93 Ceti. Alpha Ceti is later omitted from his Field Book list for Cetus.
note#28WDS measurements for chi1 do not match. 17 Cyg is just 1° northwest and ithe WDS first p.a. (73°) and sep. (26") do match. Ch1 is later omitted from his Field Book list.
note#293 Vul is not a double star. STT181 is less than .5° northwest and the WDS lists a first separation of 54" and a first position angle 5° matching Olcott's listed measurements.
note#30WDS shows large change in position angle.
note#31Position angle differs 110° from Olcott's figure - all other measurements OK
note#32Orbit appears short. The first PA given in WDS is 213° - very close to Olcott's
note#33It appears Olcott mistook SHJ 45 for omicron2. SHJ 49 is 1.2° northeast of omicron2 and is a triple that matches the measurements given by Olcott
note#34STF 422 is in Taurus and not Eridanus
note#35WDS first and last position angles (270° - 66°) show orbit to be short - thus large difference in position angle with Olcott's figure.
note#36This star is marked by a bracketed 4 in Norton's Star Atlas (6th edition - 1939). Using map #8 of that atlas and the WDS, I identified it as Bur 17 in Lepus. In the WDS the first position angles match those measurements given by Olcott
note#3731 Hydrea is tau whose WDS measurements are no match and wrong location. Using the chart and measurements from Olcott, I determined it to be S 579 in Hydra
note#38Position angle differs 256° from Olcott's figure - all other measurements OK
note#39Omicron2 is a very tight double. However, there are two stars, close in magnitude, parallel to o1 and o2 and of equal distance apart and are just 1.2° to the northeast. I believe Olcott mistook these two stars for o1 and o2 and mistakenly labeled the triple star SHJ 49, o2.
note#40Separation has narrowed from 1.7" in Olcott's day to 1.1" today. Split is now beyond resolution limit of 3 inch refractor
