$^a$~{The last character "$X$'' is only present when two sources with the same position have
to be distinguished (see text, Sect. \ref{sec-psc-1}).} \\
$^b$~{Coordinates: the final adopted coordinates (Cols.~3 and~4) are the DENIS
ones if there is an association, or the ISO corrected to DENIS if an
observation exists but no source was associated. In the northern fields
(without DENIS), the coordinates are the 7~$\mu$m ones if they exist, or
the 15~$\mu$m ones for the sources in FB fields, and the 15~$\mu$m
corrected to 7~$\mu$m for the sources detected only at 15~$\mu$m in the FC
fields. When no DENIS association exists, RAJ2000~=~RAISOGAL and DEJ2000~=~DEISOGAL.}\\
$^c$~{Only the seven last digits of the DENIS numbers have been stored,
as the three first ones are always 000.}\\
$^d$~{A value of 88.88 for a~magnitude means that this position
was not observed at this wavelength, while a value of 99.99 means that the source
was not detected at this wavelength.}
