Column description. (1): Object names. (2) {\it Spitzer} programs
from which the IRS data was taken. The identification numbers
correspond to the following programs: 2~=~{\it Spectroscopy of
protostellar, protoplanetary and debris disks}  (P.I.: J.R. Houck);
93~=~{\it Survey of PAH Emission, 10--19.5~$\mu$m} (P.I.: D. Cruikshank);
172/179~=~{\it From Molecular Cores to Planet-Forming Disks}, (P.I.: N.
Evans);  3303~=~{\it The Evolution of Astrophysical Ices: The Carbon
Dioxide Diagnostic} (P.I.: D. Whittet). (3) Total IRS exposure time
accumulated for each object in the short-high configuration. (4)~Observing strategy, i.e. the number of exposures, $n_{\rm exp}$, the
number of {\it data collecting events} (DCE) per exposure, $n_{\rm dce}$, and the exposure time of each DCE, $T_{\rm dce}$. For
targets observed by multiple programs these figures are reported for
each program. (5)  DROXO source number from Pillitteri et~al. (2009)
for objects detected in the DROXO data. (6)  Distance, in arcmin, from
the {\it XMM-Newton} optical axis during the DROXO exposure. (7)
Exposure times for the three EPIC detectors (PN/MOS1/MOS2); missing
values indicate that the source was outside the detector FOV.
