All Tables

Table 1: Lupus 3 observation log during $\it {XMM-Newton}$ revolution 685.
Table 2: Counterparts to X-ray sources detected in the EPIC field of view. Column [1] gives the identifying numbers of the sources. Columns [2] and [3] provide the identifiers of IR counterparts from the IRAS and 2MASS catalogues. Columns [4]-[6] provide the identifiers of visible counterparts (with prefix "[KWS97]TTS'' or "Lupus 3'' from Krautter et al. 1997; with prefix "SZ'' from Schwartz 1977; with prefix "[CFB2003]Par-Lup'' from Comeron et al. 2003; with prefix [GSC] from the Guide Star Catalogues; with prefix [LEM]Lup from Lopez Marti et al. 2005). The identifiers of previous X-ray detections are indicated under Col. [7]. The B, V magnitudes (Ochsenbein 1974; Mermilliod 1987) and spectral types (Houk & Cowley 1975; Jaschek 1978) of the counterparts are given in Cols. [8]-[10], respectively.
Table 3: Best-fit parameters to the EPIC spectra using a two components MEKAL model (Mewe et al. 1985) with variable abundance and with a hydrogen column density derived from the visual extinction.
Table 4: X-ray luminosities of the X-ray brightest T Tauri stars detected in the Lupus 3 "star-forming'' region in the 0.3-2.0 keV and 2-4.5 keV energy bands corrected for interstellar absorption.
Table 5: Properties of known low-mass TTS in the EPIC field of view. Column [2] is the source name (with prefix "SZ'' from Schwartz 1977, "TTS'' from Krautter et al. 1997, and "Par-Lup'' from Comeron et al. 2003). Column [3] gives the spectral type. Columns [10] and [11] provide the the H $_{\rm\alpha }$ equivalent width and the $\Delta$ (H-K) color excess from Hughes et al. (1994), Wichmann et al. (1997b), and Comeron et al. (2003).
