Even if H1 had been brought back to low noise before the week-end, the SensMon was not properly showing the range. This was due to a change in the whitening filters in CAL_DELTAL_EXTERNAL_DQ that happened last week (see  Sheila's entry ). John Z updated SensMon to take the new filters into account (thanks John), so the range monitor is back, and the summary pages show it correctly.
