Potential outliers in county-level data -- excessive values of m50.

• For Guadalupe County, New Mexico, m50, the median of the max-distance mobility, show the following statistics: median 613 Km, minimum 286 Km, maximum 702 Km. This is for a median sample size of 154.

• There are 3 further counties where the median values for m50 over the complete time series so far is of similar order of magnitude. Specifically Culberson County, Texas and Quay as well as Hidalgo County in New Mexico.

• For Carbon County, Wyoming, m50 shows a median of 16 Km. However, there's a maximum of 240 Km. The sample size for this day (2020-03-11) is 448.

Given the methodology, all of these values for m50 seem rather large. (E.g. moving 600 Km away from your starting point in a single day for the sample median in a single day.)
