Uwagi: (*) - gwiazdka przy nazwisku autora z UZ oznacza, że w danej publikacji podano afiliację autora inną niż UZ.

[N] - liczby punktów w nawiasie kwadratowym [ ]. Pojawia się przy artykułach w czasopismach, które opublikowano przed rokiem 2009. Dla tych publikacji system podaje liczbę punktów, która obowiązywała w roku 2009 niezależnie od roku publikacji.

[?] - znak zapytania zamiast liczby punktów. Pojawia się przy artykułach w czasopismach. Sygnalizuje, że w systemie SKEP nie znaleziono wyceny punktowej danego czasopisma na ministerialnej liście czasopism punktowanych.

Szczegółowe zasady obliczania punktów za publikacje w systemie SKEP znajdują się tutaj.

[C] [D] - dotyczy publikacja za lata [2017 - 2018] oraz [2019 - 2020]
C - Liczba punktów publikacji przypadająca na pracownika
D - Część slotu przypadająca na pracownika

Uwaga: W przypadku gdy pracownik zadeklarował również dyscyplinę dodatkową, po znaku "/" znajdują się analogiczne dane dotyczace dyscypliny dodatkowej.
