APX 75 This source is located relatively far off-axis in the AP108 field and APX 75 lies midway between cluster members AP97 and AP98. APX75 may represent APX 75 an unresolved detection of these two cluster members. APX 78 A is a galaxy. APX 79 ill-defined source, near rib. APX 80 A is a close double with a red secondary. APX 81 HE 523, the likely optical counterpart, is a proper motion nonmember APX 81 (Prosser et al., 1996AJ....112.1570P, Table 12), spectral type A8 APX 81 (Heckmann et al. 1956AN....283..109H). 'A' is of interest as it has APX 81 photometry acceptable for membership (Table 7). APX102 object appears to be possibly a galaxy or a double source. APX105 This source is ill-defined as it lies near/on support structure ring APX105 (rib). HE 642 is a proper motion nonmember spectral type K0 (Heckmann et APX105 al., 1956AN....283..109H). APX108 source is near rib. APX110 At 30' off-axis, this X-ray source appears somewhat extended or possibly APX110 blended with a nearby weaker source(s). No counterparts with photometry APX110 acceptable for cluster membership were found at APX110's computed APX110 position. However, during photometry of this field, a faint red star APX110 located 2-3arcmin from the X-ray position was observed and measured for APX110 photometry. This star, identified as 'APX110M', has photometry APX110 acceptable fo membership: (V,V-I_K_)=(18.81,3.07). Its optical APX110 position is estimated as RA=3:22:47.4, DE=50:29:53 (2000). A APX110 low-dispersion spectrum (Table 6) reveals relatively strong H{alpha} APX110 emission. A separate finding chart for APX110M is provided at the end APX110 of the charts provided. Possibly either a cluster member or an active APX110 late-type field star, its association to APX110 or another X-ray source APX110 cannot be determine from the present observation. APX112 source is near/on rib. APX113 this source is located far offaxis in the HE633 field. APX113 lies about APX113 4arcmin north of APX7 and may represent a redetection of this source. APX125 A is a close double. APX131 APX131A=20-758 from Prosser (1991). 20-758 was not APX131 considered in the membership study of Prosser (1991,1992) APX131 because its measured proper motion fell beyond APX131 the 1.25arcsec/cent circular region considered for proper motion APX131 candidates. The relative proper motion components for 20-758 are: APX131 mu.x=1.82+/-1.12, mu.y=-3.70+/-2.53. Note the relatively large error in APX131 the y-component. APX138 A appears as a close double in CCD B-band image. APX139 A relatively strong source, C is of interest due to its location near APX139 the X-ray position and to its extremely red color. The corresponding APX139 L_X_/L_bol_ ratio however is inconsistent with cluster membership. APX140 F appears to be either two close stars or a galaxy; no accurate APX140 photometry could be obtained due to a bad column on CCD frame. APX143 B may possibly be a close double with a faint secondary component. APX154 source is near/on rib. APX156 A has a faint companion to the NW. APX158 This source corresponds to the proper motion candidate 20-862, which was APX158 originally identified in Prosser (1991), APX158 but ultimately not considered as a member at that time. The new BVI APX158 photometry and its detection in X-rays appear to suggest membership, APX158 although its spectral type of K4 (Prosser 1991) APX158 may be inconsistent with membership. A rapid rotator, intensive CCD APX158 V-band photometric monitoring of APX158 was performed during Dec. 1995 APX158 using the Whipple Observatory 1.2m telescope at Mt. Hopkins, AZ; 100 APX158 observations over three nights were obtained. The observations reveal a APX158 period of 6.19hrs and amplitude {DELTA}V~0.04mag; a phased light curve APX158 is shown in Fig. 7. APX162 A galaxy is located near the X-ray position and is indicated with an APX162 arrow. An accurate mag./color could not be determined from available APX162 data. Low-dispersion MMT spectra obtained by C. Foltz of APX162A/B show APX162 normal stellar spectra with H-Balmer and Ca HK absorption lines for both APX162 stars. APX164 HE 936 was originally selected as a candidate member on the basis of APX164 proper motion (Heckmann et al., 1956AN....283..109H). However it appears APX164 to be a nonmember on the basis of available photometry and radial APX164 velocity observations. APX165 HE 951 is a proper motion nonmember, spectral type G3 (Heckmann et al., APX165 1956AN....283..109H). APX169 A galaxy in the field of view is indicated by an arrow. APX178 weak source, possibly spurious. APX184 A is a close binary, separation ~1.5arcsec. APX186 no photometry is available for the bright star in the circle. APX191 possible galaxy indicated by arrow. APX197 Comparison of current CCD image and older Palomar scan suggest that star APX197 B exhibits a small proper motion displacement. APX203 HE1121 is a proper motion nonmember, spectral type G1 (Heckmann et al., APX203 1956AN....283..109H).
