H5-index is calculated based on the articles published by a journal in the last five years. This h is the highest number of articles that have been cited h times during the period. For example, a journal has an h5-index of 50 meaning that 50 of its articles published in the last five years have been at least cited 50 times each.
H5-median is the median number of citations for the articles that compose the h5-index of a journal.
