Attention ! fix of a confusion in the numbering of the NIKA2 runs !
* If you whish to reach the 2-8 October 2018 Pool data page, this is actually the NIKA2 run 22 (not the 21); you need to click on this link: Calibration : Calibration Observation Plan & Summary
* For the 18-25 September 2018 test run, which is the real NIKA2 run 21, there is no specific Calibration wiki page; but be aware that all information of both the run 20 (Sep 5-6) and 21 (Sep 18-25) are gathered in the wiki pages that contain the name Nika2Run20.
