Notes. The last column is the 4σ upper limit to the circular polarization of ϵ Eridani. The two observations from 2020 April 05 were made with a time difference of 3.6 h. The values given for all epochs are from average images made using all the data from that day. During the flare of 2020 April 15, the 10.0 GHz flux density reached a value of 165±12 μJy and the upper limit for the circular polarization was ≤17%. The value of the 33.0 GHz flux density quoted for 2020 May 18 is a 4σ upper limit.
