All Tables

Table 1: Parameters of HP-1 given in the literature.
Table 2: Positions and magnitudes. For each star, the first line lists the original magnitudes while the second one gives dereddened magnitudes adopting the reddening law by Dean et al. (1978) and Rieke & Lebofsky (1985).
Table 3: Log of the spectroscopic observations carried out on 2001 July 5-6 (Julian date 2 452 095, 2 452 096). The quoted seeing is the mean value along the exposures.
Table 4: Photometric stellar parameters derived using the calibrations by Alonso et al. (1999) = AAM99 for V-I, V-K, J-K, bolometric corrections, bolometric magnitudes and corresponding gravity log g, and spectroscopic parameters.
Table 5: Abundance uncertainties for a $\Delta T_{\rm eff} = 100$ K, $\Delta$ log g = +0.3, $\Delta v_{\rm t} = 0.2$ km s^-1 and corresponding total error. The errors mean the difference in abundance that needs to be added in order to fit the observed spectrum. The values given are a mean derived from the errors from each line.
Table 7: Final abundance ratios [X/Fe] of the program stars, compared to those of the metal-poor bulge clusters UKS 1 (Origlia et al. 2005) and Terzan 4 (Origlia et al. 2004). In the 2nd column the solar abundances adopted are reported. No. corresponds to the number of lines used.
Table 6: Abundance ratios derived and atomic parameters adopted.
Table A.1: Fe I and Fe II line list, wavelength, excitation potential, damping constant, and gf-values. For HP1-3, Equivalent widths were measured using both DAOSPEC and line-by-line with IRAF.
