Notes.

(a)

The SFR has been corrected for lensing and for the dust attenuation using the extinction measured from the integrated spectrum.

(b)

The radius corresponds to , where a and b are the semi-major and semi-minor axis. The typical error on the size of the clump is about 10%.

(c)

Since the Hβ emission line is only detected in the clump 1, the Hβ flux has been derived from the Hα flux using a Hα/Hβ ratio of 2.86 and the AV measured from the integrated spectrum.

(d)

σmed is the median dispersion value of the spaxels inside each clump. The errors correspond to 95% confidence range.

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.

Initial download of the metrics may take a while.
