I noticed that Wikipedia lists the climate on Gale Crater per “month”:
None of the sources listed contain the information included in the table. I find it particularly puzzling that the year in this table is divided into 12 months which thus should be an average 668.6/12=55.7 sols each. Proposals for timekeeping on Mars may divide the year into 24 months, but simply counting the 668.6 sols in analogy to day-of-year counting is, as far as I know, more common.
What does it mean to state that the average high temperature in Gale Crater in February is -18°C? Does this have any meaning, or is this just an example flawed original research creeping into Wikipedia?
