SJR
The SJR is a size-independent prestige indicator that ranks journals by their 'average prestige per article'. It is based on the idea that 'all citations are not created equal'. SJR is a measure of scientific influence of journals that accounts for both the number of citations received by a journal and the importance or prestige of the journals where such citations come from
It measures the scientific influence of the average article in a journal, it expresses how central to the global scientific discussion an average article of the journal is.

External Cites per Doc Cites per Doc
Evolution of the number of total citation per document and external citation per document (i.e. journal self-citations removed) received by a journal's published documents during the three previous years.
External citations are calculated by subtracting the number of self-citations from the total number of citations received by the journal’s documents.
