Notes on Manitius's version of Ptolemy's catalog ------------------------------------------------------------------------------- - The global numbering from Baily's version has been added to the file for convenience. - The catalog does not restart the numbering by constellation at 1 for informes stars. The file does, for compatibility with the other versions. The conversion is easy, knowing the number of the first informis in each constellation from the following table: UMi 8 | UMa 28 | Cep 12 | Boo 23 | Her 30 | Cyg 18 | Per 27 | Oph 25 Aql 10 | Ari 14 | Tau 34 | Gem 19 | Cnc 10 | Leo 28 | Vir 27 | Lib 9 Sco 22 | Aqr 43 | Psc 35 | CMa 19 | Hya 26 | PsA 13 - The 'H' identifiers correspond to Heis's catalog (note (4) p. 400). Eduard Heis, "Atlas Coelestis Novus" (Cöln, 1872). https://archive.org/details/atlascoelestisn00heisgoog The Ambronn identifiers correspond to J. Ambronn & R. Ambronn (Dr. L. Ambronn, Ed.), "Sternverzeichnis Enthaltend Alle Sterne bis zur 6.5ten Grösse für das Jahr 1900.0" (Berlin: Springer, 1907). - Features of the original not captured in the file or otherwise noteworhty [ and their resolution ] 147 Her 29 : no data, same star as 96 Boo 9 [ copied data from 96 Boo 9 ] 191 Per 1 : name is Per..h (Bayer nebulosity NGC 869) 218 Per~ 2 : name is Heis 34 Cam 345 And 11 : longitude unreadable, assuming 25° according to other versions 401 Tau 22 : the ups.2 from Heis 101 Tau, should be ups [ kept ups.2 ] 412 Tau 33 : name is Heis 38 544 Lib~ 8 : name is Heis 2 Sco 658 Aqr 30 : name is Heis 131 707 Psc 34 : name is Heis 99 662 Aqr 34 : iot.1 most likely confused with i.1 [ kept iot.1 ] 663 Aqr 35 : iot.2 most likely confused with i.2 [ kept iot.2 ] 800 Eri 29 : Eri..d (Lacaille) is now Eri.43.ups.3 (Argelander) 802 Eri 31 : Eri..ups.5 (Bevis) is now Eri..i (Lacaille) 849 Nav 1 : Pup..e instead of Arg..e (Pup.11.j) 850 Nav 2 : Pup..iot instead of Arg..iot (Pup.15.rho) 852 Nav 4 : Pup..omi instead of Arg..omi (Pup..o) 854 Nav 6 : Pup..kap instead of Arg..kap (Pup..k) 855 Nav 7 : Pup..rho instead of Arg..rho (Pup..p) 856 Nav 8 : Pup..tau instead of Arg..tau (Pup.3.l) 857 Nav 9 : name is Heis 17 (or 47 ?) Arg but neither is a very good match 858 Nav 10 : Pup..chi instead of Arg..chi 859 Nav 11 : name is Heis 3 Arg 890 Nav 42 : 'd. i.' written 'd i.' [ fixed ] 908 Hya 15 : the lam.2 from Heis 91 Hya, should be lam [ kept lam.2 ] 920 Hya~ 2 : name looks like 'del Sit.' [ assumed del Sex ] 945 Cen 11 : name is c.9 most likely a typo for c.2 [ kept c.9 ] 1011 PsA 1 : is numbered 0 (it is a duplicate star) and the numbering of the rest of PsA is off with respect to the other versions [ used the compatible numbering ] - Stars without identification in the original. 98 Boo 11 : 866 Nav 18 : 867 Nav 19 : 881 Nav 33 : 882 Nav 34 : 960 Cen 26 : 961 Cen 27 : 968 Cen 34 : 971 Cen 37 : 1027 PsA~ 5 : 1028 PsA~ 6 : - Stars with unresolved identifications. 1000 CrA 3 : Ambronn 6062 1007 CrA 10 : Ambronn 6094 - Differences between Manitius (M) and VizieR's catalog V/61 (V) BN PID | LO (M) LA (M) MAG | LO (V) LA (V) MAG | ------------+---------------------+---------------------+ 305 Del 5 | + 33 50 | + 33 00 | 505 Vir 9 | 171 00 | 161 00 | 703 Psc 30 | 356 20 | 256 20 | ------------+---------------------+---------------------+ - Differences between Manitius (M) and John Pratt's version (J) (http://www.johnpratt.com/items/astronomy/ptolemy_stars.csv) BN PID | LO (M) LA (M) MAG | LO (J) LA (J) MAG | ------------+---------------------+---------------------+ 40 UMa~ 5 | obs | 6 | 41 UMa~ 6 | obs | 6 | 42 UMa~ 7 | obs | 6 | 43 UMa~ 8 | obs | 6 | 219 Per~ 3 | obs | 6 | 305 Del 5 | + 33 50 | + 33 00 | 311 Equ 1 | obs | 6 | 312 Equ 2 | obs | 6 | 313 Equ 3 | obs | 6 | 314 Equ 4 | obs | 6 | 494 Leo~ 6 | obs | 6 | 495 Leo~ 7 | obs | 6 | 496 Leo~ 8 | obs | 6 | 568 Sco~ 2 | 5 | 5-4 | ------------+---------------------+---------------------+
