Notes. Column (1) – object designation. and Col. (2) – Integration time in seconds; Col. (3) – Line identifications; Col. (4) – Redshifts of the Hα and [NII]λ6583 lines in the integrated spectrum. By integrated spectrum, we mean the sum of the fluxes from each pixel with an Hα line signal-to-noise ratio 3 in a specific data cube (see Col. 8 for the 3σ surface brightness detection limits). For each object, the sum for the [NII]λ6583 emission line was determined over the same aperture as for Hα; Col. (5) – Hα line velocity dispersion of the integrated spectrum of each galaxy, corrected for instrumental resolution and in units of km s-1; Col. (6) – Hα and [NII]λ6583 line fluxes of the integrated spectrum in units of 10-16 erg s-1 cm-2. and Col. (7) – star formation rate, in M⊙ yr-1, estimated from the total Hα luminosity following (Kennicutt 1998). These values have not been corrected for extinction, which is likely to increase them by a factor of a few (see text); Col. (8) – Hα surface brightness detection limit in units of 10-19 erg s-1 cm-2, at a signal-to-noise level of S/N ≈ 3. These are average values over a 3 × 3 pixel area; Col. (9) – Isophotal radius, riso, defined as . The isophotal area, Aiso, is defined as the projected area on the sky above a signal-to-noise level of 3 in the Hα data. riso is in kpc.

(a)

Denotes a 250 mas pixel scale plus adoptive optics,

(b)

a 100 mas pixel scale plus adaptive optics. No indication denotes that the data were taken without the benefit of AO, and at 250 mas pixel-1;

(c)

The [NII] line is not detected and the value given is the 3σ upper limit, for a line width equal to that of the Hα line,

(d)

the estimated line characteristics are influenced significantly by a nearby night sky line;

Current usage metrics show cumulative count of Article Views (full-text article views including HTML views, PDF and ePub downloads, according to the available data) and Abstracts Views on Vision4Press platform.

Data correspond to usage on the plateform after 2015. The current usage metrics is available 48-96 hours after online publication and is updated daily on week days.
