Today, around 18h02 UTC, I have restarted Hrec, after updating the bias file from /virgoData/Hrec/Hrec_bias_202510_with50.txt
to /virgoData/Hrec/Hrec_bias_202601_with50.txt
This update was needed to take into account that SR is aligned, while the previous bias file, used in the last months of O4c, was done with SR not aligned
and introduced a wrong online unbiasing in Hrec (as can be seen on the attached plot).
and is based on checkhrec injections done between 15h00 UTC and 16h00 UTC.
