Default header in documentclass journal

Question

I wish to submit an article to arXiv and am under the impression that if the formatting defined by \documentclass{journal} will do just fine. So my intention was to just accept whatever formatting was set up by default. Indeed it all looks very good except for the header. The header appears to be a thin horizontal line at the top of the page (all fine) with the page number appearing above that line on the right (also fine) but on the left hand side just above the line there is what looks like a solitary comma which looks very odd. Is there some optional parameter that I should have passed to the journal class to specify what should go there?

Answer 1

looking at

texdoc paper

the journal class (which is just paper class with option journal) is intended for the whole journal, including individual papers. for a single paper I think you are intended to use paper rather than journal.
