Abstract:
The 7 and 15µm observations of the Galaxy obtained by the ISOGAL
program offer an unique possibility to investigate and separate the
different populations of stars in the Galactic Plane, in particular to
study the population of low flux density YSOs which could not be
detected with IRAS.
Description:
Table 4 contains the source name, magnitudes at 7 micron and 15 micron
and identification of the point sources detected in five ISOGAL fields
with ISO. The five fields are referred in the text as A, B, C, D, and E.

Note (1): Progressive source number starting from A001 to E061
Note (2): The source name is composed of a prefix (ISOGAL-PJ) equal for all
sources an the J2000.0 coordinates as follows: hhmmss.s+ddmmss
Note (3): 7 micron magnitude; if undetected the confidence limit
of 9.5 is reported, preceded with a ">" symbol
Note (4): YSO for Young Stellar Object, cYSO for candidate YSO,
blank if not classifiable in the previous two classes
