&lt;p&gt;Wrong result, there was a mistake in the code&lt;/p&gt;</comment>

Pas de coupure en magnitude&lt;br/&gt;
Coupure en redshift &amp;lt;4.0&lt;/p&gt;

&lt;p&gt;biais=0.0034&lt;br/&gt;
nmad=0.0372&lt;br/&gt;
fraction d&apos;outliers =26.75 %&lt;/p&gt;

Merci Johanna, &lt;br/&gt;
 ca a l&apos;air tres bon ces resultats ! &lt;br/&gt;
 J&apos;ai un doute sur la definition des outliers ? &lt;br/&gt;
 Il faut le redefinir comme  abs(zcnn-zs)/(1+zs)&amp;gt; 3*sig_mad ~0.1&lt;/p&gt;

and we still see the bias problem at high z where Zcnn tend to under-estimate the redshift&lt;/p&gt;</comment>

&lt;p&gt;Ah oui j&apos;ai juste fait abs(zphot-zs) &amp;gt; 0.05. Je vais le recalculer!&lt;/p&gt;

&lt;p&gt;#####################################&quot;&quot;&quot;&lt;br/&gt;
En fait je n&apos;avais pas calcul&#233; le nmad mais la dispersion d&#233;finie par np.sum((abs(zphot-zspec)/(1+zspec)))/len(zspec) = 0.037&lt;br/&gt;
&lt;b&gt;Le nmad est en r&#233;alit&#233; &#233;gal &#224; 0.021 !&lt;/b&gt;&lt;br/&gt;
La fraction d&apos;outliers d&#233;finie par abs(zcnn-zs)/(1+zs)&amp;gt; 3*sig_mad est de 0.113 soit 11.3% &lt;/p&gt;</comment>
