STAR FORMATION IN CANIS MAJORIS
The nature of the X-ray sources

[email protected]
APPENDIX
This Appendix contains two additional figures showing the ROSAT field of the CMa R1
cloud. Table A1 lists the X-ray sources detected in this region.
Figure A1a. ROSAT observations of the CMa R1 cloud in the 0.4-2.4keV range. The 35’ inner region is
shown enlarged with a G aussian smoothing of σ = 1pixel.

Figure A1b. X-ray contours from the 2 o CMa field image of Fig. A1a superimposed on a digitized POSS(R)
plate The dashed lines show the effective ROSAT field of view.

Table A1. ROSAT sources detected in CMa. The coordinates correspond to the optical
counterpart, when available*. The position error (3rd Column) is given in arcsec and the X-ray
luminosity is given in erg/s. The R magnitude is obtained from a digitized POSS(R) plate
obtained with the M.A.M.A. (see text) and the JHK magnitudes are from the 2MASS
Catalogue.
