Abstract:
We present all ISOCAM Circular Variable Filter (CVF) spectra that
cover more than one-third of the 2.2-16.5µm spectral range of the
instrument. The 364 spectra have been classified according to the
classification system of Kraemer et al. (2002ApJS..140..389K 2002ApJS..140..389K), as
modified by Hodge et al. (2004, Cat. J/ApJS/151/299) to account for
the shorter wavelength range. Prior to classification, the spectra
were processed and recalibrated to create a uniform database. Aperture
photometry was performed at each wavelength centered on the brightest
position in each image field and the various spectral segments merged
into a single spectrum. The aperture was the same for all scale sizes
of the images. Since this procedure differs fundamentally from that
used in the initial ISOCAM calibration, a recalibration of the
spectral response of the instrument was required for the aperture
photometry. The recalibrated spectra and the software used to create
them are available to the community on-line via the ISO Data Archive.

Note (1): b: Names and coordinates reflect positions within extended
ρ Oph cores defined in Loren et al. (1990ApJ...365..269L 1990ApJ...365..269L).
Note (2): For objects with two Groups listed, the first is for the
point source and the second is for the background spectrum.
Note (3): a: Classification takes account of multiple observations
on same object with differing wavelength coverage.
Note (4): Comments use the following abbreviations:
G = extragalactic source;
Z = apparently redshifted UIR features;
Offset = name includes offsets from nominal position indicated by (0,0);
Propn = Name from original observer;
W = wrong coordinates
