Table B.1

Selection of quiescent galaxies in the redshift range 0 ≥ z ≥ 3, using the Int Wide catalogue with its labels replaced by labels derived from the NUV − r vs. r − JE or NUV − r vs. r − K colour-colour methods.

Notes. For this test the ugriz, IE, FE, JE, HE, W1, W2 and 20 cm bands were used, with detections required in all of the Euclid bands. Here, the ARIADNE pipeline was used in its fast mode. No results are shown for the NUV − r vs. r − K case in the redshift ranges 2 – 2.5 or 2.5 – 3, due to the very low number of sources labelled as quiescent by this method. The columns are as follows:

(1) Redshift range in which the test was conducted;

(2) information on whether photometric redshifts were used to restrict the dataset to source in the specified redshift range ('Yes' or 'No');

(3) precision P for quiescent galaxy selection when using labels derived from the NUV − r vs. r − JE method;

(4) recall R for quiescent galaxy selection when using labels derived from the NUV − r vs. r − JE method;

(5) the F1-score for quiescent galaxy selection when using labels derived from the NUV − r vs. r − JE method;

(6) precision P for quiescent galaxy selection when using labels derived from the NUV − r vs. r − K method;

(7) recall R for quiescent galaxy selection when using labels derived from the NUV − r vs. r − K method;

(8) the F1-score for quiescent galaxy selection when using labels derived from the NUV − r vs. r − K method;

(9) precision P for quiescent galaxy selection when using labels derived from the sSFR;

(10) recall R for quiescent galaxy selection when using labels derived from the sSFR;

(11) the F1-score for quiescent galaxy selection when using labels derived from the sSFR.
