The TELPERION Survey for Distant [O III] Clouds Around Luminous and Hibernating AGN

The collection includes the FITS files of newly-obtained data used for the study “The TELPERION Survey for Distant [O III] Clouds Around Luminous and Hibernating AGN” by William C. Keel et al., submitted to Monthly Notices of the Royal Astronomical Society.

Zip files for objects in the VCV sample (and the best-observed in the Toomre merger 
sample) use object names as in the tablesin the manuscript. File names use these conventions:
Suffix o3.fits : narrowband F510 filter including redshifted [O III] emission
Suffix o3co.fits: as above with WCS information from the astrometry.net web service
Suffix v.fits: in the Johnson V band
Suffix vco.fits: V band, with WCS coordinate metadata
Suffix v2o3.fits: V image resampled to the same WCS coordinate grid as the F510 image, when the two are from different cameras and not related by a simple shift.
vscale.fits: resampled V image scaled for continuum subtraction from the F510 data.
vs.fits: as above, with small shifts accounting for asymmetric point-spread functions (PSFs).
vg.fits, vsg.fits: as above images, with Gaussian blur for first-order accounting of PSF differences.
diff.fits - difference image nominally representing pure [O III] emission. There may be a version numberb(diff2, diff3) if multiple iterations were done. These may also have names such as diff2g.fits, diff1s.fits if Gaussian blur or small shifts were done as for vs.fits, vsg.fits files.

"flat" denotes that a low-pass spatial filter (such as a large median) has been used to reduce the effects of stray light on a difference image.

Toomre.zip includes F510 and V images for those galaxies in the Toomre-sequence sample not included in the SARA data.

LongSlit.zip includes reduced two-dimensional spectral data as detailed in the paper. _abs indicates that the data values are calibrated to intensity units (ergs/(cm^2 s Angstrom)) using standard-star observations; otherwise they are in instrumental units. Wavelengths are in Angstroms, in air. Data using the ADAM instrument are prefixed with that string.

Tunable.zip includes the results of the MaNGAL and SCORPIO tunable-filter observations. The string “5007net” denotes that the continuum (“cont”) has been subtracted; “5007” by itself marks images including the [O III] line  but not yet continuum-subtracted.
