Appendix A: Supplementary electronic material

This Appendix gives more detailed information about optical observations, the X-ray spectrum, the redshift distribution, and the brightness of spectroscopically classified objects in the field of 1007.

Table A.1:   LBT image parameters.

Redshift distribution of galaxies in the field of 1007 observed with VLT-FORS2-MXU (see Table A.2). The inset is a blow-up comprising the redshift range covered by likely cluster members.

Table A.2:   Spectroscopically confirmed cluster member galaxies (upper part) and nonmember galaxies targeted by VLT-MOS spectroscopy sorted by increasing z-band magnitude.

\end{figure} Figure A.3:

VLT/FORS2 R-band image with slit positions identified (north is top, east to the left). Labels are the same as in the first column of Table A.2. Likely cluster members are encircled, unrelated classified objects (lower section of Table A.2) are framed with squares, objects that were positioned on slits but could not yet be classified are framed with rhombs.
