ADC_Keywords: Stars, nearby ; Proper motions ; Photometry, infrared Keywords: solar neighborhood - stars: distances - stars: statistics Abstract: We report the discovery of 152 new high proper motion systems (µ≥0.4"/yr) in the southern sky (δ=-47° to 00°) brighter than UKST plate R59F=16.5 via our SuperCOSMOS-RECONS (SCR) search. This paper complements Paper XII (2005, Cat. J/AJ/129/413) in the Solar Neighborhood series, which covered the region from δ=-90° to -47° and discussed all 147 new systems from the southernmost phase of the search. Among the total of 299 systems from both papers, there are 148 (71 in Paper XII (2005, Cat. J/AJ/129/413), 77 in this paper) new systems moving faster than 0.5"/yr that are additions to the classic Luyten Half Second sample (1979, Cat. I/87). These constitute an 8% increase in the sample of all stellar systems with µ≥0.5"/yr in the southern sky. Description: Coordinates, proper motions, and plate magnitudes have been extracted from SuperCOSMOS (Hambly et al., 2001MNRAS.326.1279H) for the new HPM systems. These data are listed in table2.dat. Infrared photometry has been used to extend the color baseline, which allows more accurate photometric distance estimates for red dwarfs and permits a reliable separation of the white and red dwarfs. The infrared JHKs photometry has been extracted from the Two Micron All Sky Survey (2MASS, II/246) via Aladin. File Summary:

Note (1): Proper motion intervals, defined as follows: A = SuperCOSMOS-RECONS sample with µ≥0.5"/yr B = SuperCOSMOS-RECONS sample with µ between 0.4"/yr and 0.5"/yr Note (2): Errors in the coordinates are typically ±0.3", and errors in the proper motions are given. Note (3): Errors in position angle are usually ±0.1°. Note (4): Magnitude errors are ∼0.3mag or better for m>15 and actually get larger at brighter magnitudes due to systematic errors Hambly et al. (2001MNRAS.326.1295H). A few plate magnitude values are missing because of blending problems that preclude accurate magnitude determinations. Note (5): In nearly every case, the errors are smaller than 0.03mag. Exceptions include objects with Jmag>15, Hmag>14.5, and Ksmag>14, where the errors are 0.05mag or greater. In one case, SCR 1246-1236, the error is null for Ksmag, and the value is therefore unreliable. Note (6): If only one color was available for a distance estimate, no distance is reported because the single color falling within the bounds of the relations is possibly aberrant. Note (7): all stars marked with the closing bracket have distances estimated to be 90pc or greater, but they are, in fact, likely to be much closer than estimated (i.e. the distances are incorrect), so their distance estimates are flagged to distinguish them from presumed dwarfs whose distance estimates are plausibly accurate. Note (8): Additional notes, defined as follows: a = distance likely overestimated because object is a subdwarf or white dwarf candidate (see Section 5.3); b = probable white dwarf; c = all colors too blue for distance relations; d = separation 2.5" at position angle 266.2°; e = no distance estimate reported because only one color was available within the bounds of the relations; f = common proper motion with LTT2976; g = White dwarf; Ks unreliable; h = Common proper motion with CD -42 10084; i = Common proper motion with L 408-087; j = not detected during automated search due to faint limit but noticed to be a common proper motion companion during the visual inspection, blended on all four plates; k = Common proper motion with LTT 8495;
