Follow-up observations at other wavelengths revealed that some of these sources feature unusually large column densities, long pulsations, and other interesting characteristics. We investigate where new and previously-known sources detected by ISGRI fit in the parameter space of high-energy objects, and we use the parameters to test correlations expected from theoretical predictions. For example, the influence of the local absorbing matter on periodic modulations is studied for Galactic High-Mass X-ray Binaries (HMXBs) with OB supergiant and Be companions. We examine the spatial distribution of different types of sources in the Milky Way using various projections of the Galactic plane, in order to highlight signatures of stellar evolution and to speculate on the origin of the group of sources whose classifications are still uncertain. Description: File table1.dat contains the names of all 499 sources detected so far by ISGRI, with the most precise coordinates (J2000) and error radii available in the literature. Classifications are provided for all sources. When available, the published photoelectric absorption in the X-rays, distances/redshifts, and pulsation and orbital periods are also listed.

Note (1): Most sources have more than 1 name owing to detections by various instruments operating at different energies. As in Ebisawa et al. (2003, cat. J/A+A/411/L59), we selected names that are commonly used in high-energy astrophysics and that are accepted as an identifier in SIMBAD. This eases comparisons with other catalogs. Note (2): Source positions are from the X-rays unless a more accurate position at other wavelengths is known for a confirmed counterpart. Note (3): Column densities were gathered from the literature whenever a model fit to the X-ray spectrum required an absorption component. Extracting a single NH for a source and comparing this value to those of other sources is not a straightforward exercise since intrinsic column densities are not static. A measurement made during flaring or quiescent periods, or at different orbital epochs, will heavily influence the NH. The geometry of the system, the energy range of the satellite that gathered the data, and the model used to describe the resulting spectrum also affect the NH value. Therefore, the uncertainties are often large or only upper limits are provided. Whenever possible, we selected the NH value of the model that best fits a recent X-ray spectrum taken with a telescope that covers the soft X-ray domain well. Note (4): Spin periods and/or orbital periods have been reported for a large number of Galactic objects detected by ISGRI. Some systems are known to spin down, so we selected the most recent value from RXTE whenever possible, even though this level of precision is not needed for the purpose of our study. The spin period can refer to the spin of the NS in X-ray binaries, or to the spin of the White Dwarf in CVs. The catalogs of Liu et al. (2000-2001, Cat. V/106), and the systematic analysis of RXTE data by Wen et al. (2006ApJS..163..372W) are among the main references of spin and orbital periods in this work. Note (5): Opinions sometimes differ as to the distances of some Galactic sources. We favored distance measurements that were recent, precise and that were the least model-dependent. Even so, the distance uncertainties quoted in the literature can be large. The distance measurements are from, among others, White & van Paradijs (1996ApJ...473L..25W), Grimm et al. (2002A&A...391..923G), Jonker & Nelemans (2004MNRAS.354..355J), Bassani et al. (2006ApJ...636L..65B), Beckmann et al. (2006ApJ...638..642B), or from references in Liu et al. (2000-2001, cat. V/106). Note that the distances in Grimm et al. (2002A&A...391..923G) sometimes represent an average over several competing distance estimates. Note (6): Source classifications are based on the concensus opinion in the literature. Peculiar behaviour, such as quasi-periodic oscillations, transience, and Z-track or Atoll shapes, are also noted since they can help us distinguish between systems within the same class. If the source classification has not yet been confirmed, it is simply called "unclassified". The transient identification of a source is given by any of the following: 1) the label was assigned by its discoverers or by other authors (e.g. "Discovery of a new transient IGR J...''); 2) the source has not been detected by anyone else since its discovery announcement, e.g. it is not listed in the all-data, all-sky catalogs of Bird et al., 2006, Cat. J/ApJ/636/765, 2007ApJS..170..175B); 3) the source is detected only in mosaic images of a single or a few consecutive revolutions according to Bird et al. (2007ApJS..170..175B), but not in their all-data mosaic images.
