Notes.

(a)

Numbers listed in this table are only suitable for sources situated in the regions of the field with exposure time higher than that reported in this column.To convert the PACS coverage maps provided in the released package into hrs/pixel, users should multiply them by 1.06 × 10-2.

(b)

The 1σ flux density levels have been computed from 10 000 random extractions on residual maps.

(c)

Number of sources above a given S/N threshold.

(d)

Completeness is defined as the fraction of simulated sources with Sin ~ 3(5)σ and extracted with a flux accuracy better than 50%, i.e., − 0.5 < (Sout − Sin)/Sout < 0.5.

(e)

Contamination is defined as the fraction of simulated sources introduced with Sin < 2σ but extracted with Sout > 3σ.

(f)

Flux densities above which our catalogues are 80% complete.

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.
