The exceptions: V17, V84, V88 and V173, are explained in the notes on individual stars. 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, SXPHE and Blazhko (Bl) 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: Walker & Nemec (1996) found that Fourcade and Laborde had misidentified V17 and V88 which are Sarajedini's RR stars #2 and #14 respectively. The x,y positions we list for these stars have been revised using the corrections listed by Walker & Nemec in footnote #4 on page 2034 of their paper. V35, V68, V75, V79, V99, V100, V102, V107, V110, V113, V114, V115, V117, V118, V120, V121, V122, V123, V125, V128: The NV classification for these stars was made by Clement et al. (1979, AJ 84, 217) V84: The sign of the y coordinate (-41.53) listed by Fourcade & Laborde in their 1969 paper (Mem. SA Ital Vol XL, 1) is incorrect. It does not agree with the position labelled on their ID chart. According to Samus (2009, private communication), y for V84 should be +41.53 arcsec. The incorrect sign for y was also listed by Sawyer Hogg (1973) in her 3rd catalogue and in our previous electronic catalogues. V88: See V17 V91: The NV classification for V91 by Clement et al. (1986, AJ 92, 825) V127: Variability type (RR) for V127 from Sarajedini (1993) V39, V60, V67, V86, V94, V101, V104, V105, V116, V119, V124, V126, V129: The NV? 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: NV? for V152 because Clement et al. could not derive a period and Sarajedini did not detect significant variations. V173: V173 a foreground RR1 was discovered by Walker & Nemec (1996); they published the x,y position for their new variable. ======================================================================== Discovery of the variable stars in IC4499: V1-129 (confirmed) and V130-170 (suspected) by Fourcade An ID chart was published and x,y coordinates listed for V1-169 by Fourcade & Laborde (1969, Mem Soc Ast Ital, Vol XL, p1) and for V1-34 in Atlas y Catalogo, Cordoba (1966) by Fourcade, Laborde & Albarracin. Fourcade et al. (1974, Peremennye Zvezdy Pril, Vol 2, No. 7, p3) 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. Fourcade's suspected variables (130-170) are not listed in the above table unless they were discussed by another author in a subsequent paper. V171 is RR star #26 of Sarajedini (1993, AJ 105, 2172), also identified as V1575 by Walker & Nemec (1996, AJ 112, 2026) - see Figure 3 and Table 8 of the Walker & Nemec paper Sarajedini's RR star #2 and #14 were subsequently shown by Walker & Nemec to be Fourcade's V17 and V88. V172 by Sarajedini (1993) = his blue straggler #4, identified as BS#4 in Fig 3 of the paper by Walker &Nemec (1996). Sarajedini (1993) noted the possibiity of variation in two other blue stragglers, but Walker & Nemec did not confirm their variation. V173 by Walker & Nemec (1996), a foreground RR Lyrae identified as star #434 in Fig 2 of their paper. They also derived this star's x,y position. =====================================================================
