Abstract:
We have previously shown that a blue (warm) 60 to 25µm infrared
colour provides a powerful parameter for discriminating between AGNs
and normal galaxies and that the far-IR spectrum is therefore an
efficient tool for finding new AGNs (de Grijp et al.,
1985Natur.314..140D 1985Natur.314..140D) Here we present a list of such AGN candidates
based on warm IR sources from the IRAS Point Source Catalogue (PSC,
Cat. II/125). Identification data and finding charts are also given.
In addition the list of warm IRAS sources is supplemented by a
compendium of data from the IRAS PSC on detected sources identified
with previously known AGNs whose infrared spectra do not bring them
within our colour selection criterion

Note to table1: Sources were selected on position (high galactic latitude,
not in Magellanic and colour (25 to 60µm spectral index between
1.5 and 0.0). All sources satisfying these criteria are included, even
when optical identification indicates them to be non-extragalactic objects.

Note (1): the classification uses the following abbreviations:
BL = BL Lac object
S1 = Seyfert 1 (including QSO)
S2 = Seyfert 2
S3 = LINER
H2 = galaxy with nucleus HII-region
PN = planetary nebula
RN = reflection nebula
DN = galactic dark cloud
ST = star
LH = local H2 region in the galaxy
GAL = galaxy
EF = empty field
M31 = M31 type
Note (2): Redshifts from Veron & Veron (1985, See Cat. VII/188), Palumbo
et al. (1983, See Cat. VII/99), de Grijp et al. (1986, A&A, in prep.)
Note (3): Matches with published catalogues using the same catalogue
numbering convention as given by the IRAS Catalogue (See II/125).
The non-standard "ZG" acronym stands for Zwicky's catalog of galaxies
(see e.g. cat. VII/190)
