(2001) and for V38-52 are from Mazur et al. (1999). The non-membership status of the EC variables V43, 45 and 52 was confirmed by Rucinski (2000). The RA and dec for most of V1-52 are from Samus et al. (2009); the exceptions are V11, 23, 24, 26, 28, 29, 32 and 38-41 which are from Mazur et al. (1999). =================================================================== Notes on individual stars V4, V9: The non-variable status of these variables was first noted by van Agt (1961) and confirmed by Clement et al. (1995). Mazur et al. (1999) concurred that V4 was probably constant, but V9 was outside of their field. V32: Clement et al. (1995) classified this star as non-variable, but Mazur et al. (1999) showed that it was an RR0 variable. They concluded that Clement et al. must have measured the wrong star. V45: The RA and dec are from Samus et al. (2009) who stated that the RA that Mazur et al. (1999) derived (17:32:52.7) was off by 2 minutes. Samus et al. identified the star with a 2MASS source. =================================================================== Discovery of the variable stars in NGC 6362: V1-15 Woods (1919) with x,y coordinates According to Shapley (1930), Woods discovered 17 variables in NGC 6362, but it appears that 2 were unpublished and there is no further information about them. In the 3rd catlogue, Sawyer Hogg (1973) mentioned a field variable announced by Shapley (1922) V16-31 van Agt (1961) with x,y coordinates and an ID chart for all of V1-31 (excepp V4 and V9). van Agt also made small revisions to some of the x,y coordinates derived by Woods (1919) V32 Fourcade et al. (1966) with x,y coordinates and ID chart for V1-32 V33 = VH 11 van Hoof (1961) with x,y coordinates and an ID chart The number V33 was assigned by Sawyer Hogg (1973) in her 3rd catalogue. van Hoof announced the discovery of seven other variables, but these were all independently discovered by van Agt (1961) so Sawyer Hogg adopted van Agt's numbering system for her catalogue. All of the epochs, periods and magnitudes listed for the NGC 6362 variables in her 3rd catalogue were from van Hoof's paper. V34-52 Mazur et al. (1999) with RA, dec and individual finder charts ------------------- Pietrukowicz et al. (2008) searched for dwarf novae in NGC 6362 and found none. Their search was based on observations made on 104 nights, spanning 7 years, from 1999 to 2005. =============================================================== References Fourcade, C. R., Laborde, J.
