For example, "BD-01 0004" or "BD+35 4290". For CD objects: Use [[Category:Durchmusterung objects|CD-ZZ NNNNN]], where ZZ is a two-digit declination, and NNNNN is a five-digit number (with leading zeroes if necessary). For example, "CD-03 00004" or "CD-31 19142". For CP or CPD objects: Use [[Category:Durchmusterung objects|PD-ZZ NNNNN]], where ZZ is a two-digit declination, and NNNNN is a five-digit number (with leading zeroes if necessary). For example, "PD-55 10147" or "PD-73 02296".
