Also IC 4499 and M3 are the only Galactic Oosterhoff type I clusters that have double-mode RR Lyrae (RR01) variables. The RA and dec n the above table are from Samus et al. (2009). All of the periods, magnitudes and amplitudes in the above table were taken from the paper by Walker & Nemec (1996). In addition, the variability types we have listed for all of the stars classified as RR0, RR01, RR1, RR2 and SXPHE are the types adopted by Walker & Nemec. ====================================================================== Notes on individual stars V4: The y coordinate listed for this star by Sawyer Hogg (1973) and in our previous electronic catalog had a minus sign that was incorrect. (The correct value is y = +14.03 arcsec) V17, V88: Walker & Nemec (1996) found that Fourcade & Laborde (1969) had misidentified V17 and V88 which are Sarajedini's RR stars #2 and #14 respectively. In footnote #4 on page 2034 of their paper, Walker & Nemec indicated the correct positions of these two stars. V35, V68, V75, V79, V99, V100, V102, V107, V110, V113, V114, V115, V117, V118, V120, V121, V122, V123, V125, V128: The CST classification for these stars was made by Clement et al. (1979) V84: The sign of the y coordinate (-41.53) listed by Fourcade & Laborde (1969) was incorrect according to Samus et al. (2009). It does not agree with the position labelled on their ID chart. The incorrect sign for y was also listed by Sawyer Hogg (1973) in her 3rd catalogue and in our previous electronic catalogues; y for V84 should be +41.53 arcsec. V91: The CST classification for V91 by Clement et al. (1986). V127: Variability type (RR) for V127 from Sarajedini (1993) V39, V60, V67, V86, V94, V101, V104, V105, V116, V119, V124, V126, V129: The CST? classification was assigned because these stars were in the field observed by Sarajedini (1993) and he did not detect significant variations. None of these stars were measured by the other investigators. V152: CST? for V152 because Clement et al. (1979) could not derive a period and Sarajedini (1993) did not detect significant variations. Furthermore, it was not recovered as a variable star by Walker & Nemec (1996). ======================================================================== Discovery of the variable stars in IC4499: V1-129 (confirmed) and V130-170 (suspected) by Fourcade ID charts were published and x,y coordinates listed for V1-169 by Fourcade & Laborde (1969), for V1-6 by Fourcade & Laborde (1965) and for V1-34 by Fourcade et al. (1966). Fourcade et al. (1974) also published an ID chart. Unfortunately, in the University of Toronto copy, it is inaccessible because it is folded into the binding. However, according to Samus (2009, private communication) two different stars are listed as V65 and V106 is incorrectly labelled as V108. Most of Fourcade's suspected variables (130-170) were not detected as variables in subsequent studies and are therefore not listed in the above table. Clement et al. (1979 - Table 2) summarized their findings with regard to these stars. V153 and V167 were later recovered as RR Lyrae variables by Walker & Nemec (1996). V171 is RR star #26 of Sarajedini (1993 - Fig. 1 and Table 3) It was also identified as V1575 by Walker & Nemec (1996 - Fig 3 and Table 8). The number V171 was assigned in the electronic catalogue of Clement et al. (2001). Sarajedini's other two "new" RR Lyrae variables, #2 and #14 were later shown by Walker & Nemec to be Fourcade's V17 and V88; they had been misidentified on Fourcade's original finding chart. V172 = blue straggler #4, a suspected BSS variable (Sarajedini 1993) who listed its X,Y pixel numbers in Table 4 of his paper. Its variability was later confirmed by Walker & Nemec (1996) who labelled it on a chart (Fig. 3 in their paper). The number V172 was assigned in the electronic catalogue of Clement et al. (2001). Sarajedini (1993) noted the possibiity of variation in two other blue stragglers (his #2 and #16), but Walker & Nemec did not detect any variability in these stars. V173 = star #434 of Walker & Nemec (1996), a foreground RR Lyrae they identified in Fig 2 of their paper. They also derived this star's x,y position. The number V173 was assigned in the electronic catalogue of Clement et al. (2001). --------------------------------------------------------------------- Sahay et al. (2014) detected two long period variables in the field of IC 4499. They designated them as SLW1 and SLW2 and listed their RA, dec, V, I, J, H, K magnitudes and derived periods of 67 and 35 days respectively, based on V magnitudes. They tentatively classified both stars as non-members based on their location relative to the IC 4499 giant branch defined by Hankey & Cole (2011) on a K-(J-K) plot. ===================================================================== References Clement, C.
