## Atmosphere

Various commands relates to the atmosphere: the "atmospheric" calibration or chopper-wheel method, that is used to put the visibilities on a scale (see 2.3.1), the water vapor radiometer (WVR) calibration that will derive atmospheric phase correction, and the total power phase correction that was used for the PdBI before the use of WVRs.
