Appendix A: Tables of line-strength measurements

A.1 Line-strength measurements for globular clusters in NGC 3115

Tables 2 and A.1 present the line-strength measurements for globular clusters in NGC 3115. The spectra have been broadened to the Lick/IDS resolution prior to index measurements. Small offsets have been made to match the Lick system as closely as possible (see Sect. 2 for details). For a summary of the definition of Lick/IDS indices see Trager et al. (1998).

Notes: Listed are line-strength measurements in the wavelength range 4500-5450 Å for globular clusters in NGC 3115 (see also Table 1). The first line for each object shows the measured index values whereas the second line lists the associated errors. The unit for each index is given at the top in square brackets.
^a For this globular cluster we measured a Fe5335 index of $-1.24(\pm0.75)$ Å. This negative number is caused by a noisy section in the spectrum. By comparing this index with other Fe indices we established that a realistic value of the Fe5335 index for this globular cluster should be +0.3. To reflect the unertainty in this procedure we increased the error by a factor of 1.5.

A.2 Lick/IDS observations of H $\mathsfsl{\gamma_{A,F}}$ and H $\mathsfsl{\delta_{A,F}}$ indices for Milky Way and M 31 globular clusters

Since the higher order Balmer indices of Milky Way and M 31 globular clusters as measured in the Lick/IDS system have not yet been published, we list the measurements of H $\gamma_{\rm A,F}$ and H $\delta_{\rm A,F}$ in Tables A.2 and A.3. The Lick observations are described in Burstein et al. (1984), names are explained there (see also Trager et al. 1998). M 31 globular clusters were observed with the standard aperture of the Lick/IDS system ( $1\hbox{$.\!\!^{\prime\prime}$ }4 \times 4\hbox{$.\!\!^{\prime\prime}$ }0$). The MW globular clusters were observed with a long-slit of standard width that was raster-scanned on the sky to create a square aperture of size $66\hbox{$^{\prime\prime}$ }\times 66\hbox{$^{\prime\prime}$ }$ (only for NGC 6624 the aperture is $45\hbox{$^{\prime\prime}$ }\times 60\hbox{$^{\prime\prime}$ }$). Raster scans have the same spectral resolution as standard slit width scans. For the definition of the higher order Balmer indices see Worthey & Ottaviani (1997).
