(2008 AJ, 135, 1459). All of the data listed in the above table for RR Lyrae and Cepheids are from the Corwin et al (2008) paper unless indicated otherwise in the "Remarks" column in the following manner:. If the star was not studied by Corwin et al., the position listed (usually x,y coordinates in arcsec) is from the discovery paper and the source for the period, magnitude, amplitude and variability type is indicated in the "Remarks" column where: "S&S" refers to Silbermann & Smith (1995, AJ 110, 704), "Bing" refers to Bingham et al. (1984, MNRAS 209, 765), "Rosino" refers to Rosino (1969, IBVS 327), "Kadla" refers to Kadla et al. (1984, Astron. Tsirk. 1314) and "Tuair" refers to Tuairisg et al. (2003, MNRAS 345, 960) who derived the RA & dec as well. Corwin et al. (2008) also pointed out that there is some overlap among the variables listed by different authors. This confusion appears to have occurred because Tuairisg et al. (2003, MNRAS 345, 960) and Zheleznyak (2003, Ast Let 29, 599) were writing their papers at the same time. We have indicated these identities in the notes/remarks column. The data for the ZK variables and for V122, V123, V124, V125, V126, V127, V156, V157, V158, X-2, CV1, CV2 are from their discovery papers unless indicated otherwise in the notes. An identication chart and catalogue of x,y positions for most variables numbered up to 123 was publishd by Kadla et al. (1988, Izvestia Glavnaia Obs Pulkovo No. 205, p114). Please note, however, that their V113, 114, 122 and 123 are not the same stars as the ones listed in the above table. Kustner (1921, Bonn Veroff no. 15) listed x,y positions for 1137 stars in M15. His catalog numbers have been cited by many authors. ================= Notes on individual stars V27: The NV status for V27 is from Rosino (1950, ApJ 112, 221) V34: The magnitude and amplitude for V34 is from Arellano Ferro et al. (2006, Rev. Mex A&A 42, 75) and the RA, dec, period and variability type are from Corwin et al. (2008, AJ 135, 1459) V46: This appears to be the same star as V12. See the comment for V112. V72: Period, magnitude, amplitude and variability type are from Notni & Oleak (1958, Ast Nach 284, 49). They pointed out that an alternate period is 0.5984. They classifiedf the star as a type a RR Lyrae, but if the 1 day period is correct, this is unlikely. V77, V92: Tuairisg et al. (2003, MNRAS 345, 960) published data for V77 and V92, but according to their ID chart, the stars they labelled as V77 and V92 are not the same stars that Rosino (1950) identified as V77 and V92. A comparison of their RA & dec with the ones listed by Corwin et al. (2008, AJ 135, 1459) indicates that Tuairisg interchanged the coordinates for these two stars. V79, V85, V95: Rosino (1950, AJ 112, 221) announced these variables, but no further information is available. However, Zheleznyak & Kravtsov (2003, Ast Let 29, 599) confirmed that they vary. V86: The period, magnitude and amplitude listed for V86 are from Fusi Pecci et al. (1980, A&A 85, 269). The RA and dec are from Corwin et al. (2008, AJ 135, 1459) V98, V100: Period, magnitude, amplitude and variability type are from Notni & Oleak (1958, Ast Nach 284, 49). These authors listed type ab (RR0) for V100, but on the basis of the period, we have reclassified it as "RR1?". It is possible that it is type RR01. V104, V105: All the data listed for V104 and V105 are from the paper by Yu-hua, (1961, Acta Astr Sinica 9, 65), except the RR01 classification for V104 which is from Barlai (1989, Konkoly Communications Vol 10, No. 92, p151) V112: Kadla et al. (1988, Izvestia Glavnaia Obs Pulkovo No. 295, p 114) noted that this star might be V46. According to Sawyer Hogg's (1973) 3rd catalog, their magnitude range and x, y postions are similar: 15.40-16.32, +56.0, +33.2 for V46 and 15.3-16.3, +55.5, +35.0 for V112. Thus we conclude that they are the same star. Kadla et al. also suggested that V47 and V111 might be one star, but that seems unlikely. Corwin et al. (2008, AJ 135, 1459) found a separation of about 4 arcsec and derived periods for both. V122: Chu (1977, Chinese A&A 1, 302) derived a 2 hour period for V122, but this was not confirmed in subsequent investigations. Smith et al. (1979, PASP 91, 671) detected no variation. Liller & Schommer (1980, IBVS 1752) found no evidence for variations on the 2 hour time scale, but commented that there might be a signifucant difference in mean magnitude on different nights. V125 (AC 211 or X-1): The RA & Dec are Kulkarni's values for AC 211, reported by White & Angelini (2001, ApJ 561, L101). The remaining data listed for V125 are from page 148-149 of the paper by Ilovaisky (1993, A&A 270, 139). V140, V146, V147, V148, V149, V150, V151, V153, V154: The x,y coordinates are from Zheleznyak & Kravtsov (2003, Ast Let 29, 599 (2003) and the non-variable status is from from Tuairisg et al. (2003) V155: Butler et al. (1998, MNRAS, 296, 379) derived a period of 0.224 for V155, but we have not listed it because such a short period is not appropriate for an M15 RR Lyrae variable with such a large amplitude. Furthermore, a subsequent investigation (Tuairisg et al. 2003) of the variables studied by Butler et al. found a number of errors in their analysis. V161, V165, V174, V175: The periods and variability types for these stars are from Corwin et al. (2008, AJ 135, 1459), but since they did not list mean magnitudes and amplitudes, we list these data from the paper by Tuairisg et al. (2003, MNRAS 345, 960) ZK62, ZK68: RA, dec, period, amplitude and variability type are from Kravtsov & Zheleznyak (2003, IBVS 5452) The Cataclysmic variables CV1 and CV2: RA, dec, magnitude and variability type is from Hannikainen et al. (2005, MNRAS 357, 325). CV1 is their source A and CV2 is source C. ================================================= Discovery of the variable stars in M15: V1-51 Bailey (1902, HA 38) with ID chart V52-66 Bailey et al.
