ACKNOWLEDGEMENTS:


I am very much obliged to Mr.D.Kühl for the LATEX-file of the manuscript, for his general help with the tables and the charts, as well as for measuring with me the coordinates of several hundreds of objects. Without his contribution the Catalogue could not have been published in the present form. My special thanks are also dedicated to Dr.H.Hagen for the possibility of using his image processing software, especially for coordinate grids on the charts and the options for measuring coordinates. I am much indebted to Dr.D.Engels for valuable discussions and for his support in various fields. I would also like to thank Mrs.A.Müller for her help concerning the lists of coordinates used and Ms.S.-B.Kühl for her valuable work with the finding charts. I acknowledge with thanks the help of Dr.N.Christlieb with the IRAS sources including the corresponding computing programme and Mrs.P.Halilhodzic who also contributed much to the programming. I am indebted to Prof.Dr.J.Schmitt for the discussion on X-ray sources and to Dr.J.-U.Ness for his help also concerning this category of objects. I am very much obliged to Dr.L.Perek for reading the manuscript and for his constant interest concerning the Catalogue. I am thankful to Dr.W.Martin for the critical reading of the text and for his comments. I also wish to thank Prof.Dr.J.Hazlehurst and Mrs.Ch.Kohoutek for correcting the English version of the manuscript. I appreciate the support of this work by several other colleagues and last but not least the support by the Directorate of the Hamburg Observatory.

I used 714 finding charts, mainly of the Second Digital Sky Survey (DSS2) and I thank all institutions which are engaged in this project:
530 charts are based on southern plates which belong to the Second Epoch Survey of the southern sky made by the Anglo-Australian Observatory (AAO) with the UK Schmidt Telescope. These plates have been digitized and compressed by the ST ScI. The digitized images are copyright (c) 1993-8 by the Anglo-Australian Observatory Board, and are distributed herein by agreement. All Rights Reserved.
161 charts are extracted from the compressed files of the Palomar Observatory - Space Telescope Science Institute Digital Sky Survey of the northern sky, based on scans of the Second Palomar Sky Survey and are copyright (c) 1993-1995 by the California Institute of Technology and are distributed herein by agreement. All Rights Reserved. Produced under Contract No. NAS5-2555 with the National Aeronautics' and Space Administration.
Some charts are based on
(a) photographic data obtained using The UK Schmidt Telescope. The UK Schmidt Telescope was operated by the Royal Observatory Edinburgh, with funding from the UK Science and Engineering Research Council, until 1988 June. Original plate material is copyright (c) the Royal Observatory Edinburgh and the Anglo-Australian Observatory. The plates were processed into the present compressed digital form with their permission. The Digitized Sky Survey was produced at the Space Telescope Science Institute under US Government grant NAG W-2166;
(b) photographic data of the National Geographic Society - Palomar Observatory Sky Survey (NGS-POSS) obtained using the Oschin Telescope of Palomar Mountain. The NGS-POSS was funded by a grant from the National Geographic Society to the California Institute of Technology. The plates were processed into the present compressed digital form with their permission.
I obtained the data as fits-files from the Online Digitized Sky Surveys (DSS1 & 2) server at the ESO/ST-ECF Archive, using the webpage of ESO.

I thankfully acknowledge the database SIMBAD operated at CDS (Strasbourgh, France).
