We first started getting ILM4D00 trips while doing the calibration. I nudged NL GP a tad to bring these down hoping we could finish it since we were close (we were at 22 uA, going up to 30 uA).

Going to the next step in the calibration, we got a BLA trip on instantaneous loss.

A bit of steering should help narrow positions at 1H04A/B

Initial reaction was to look at the Matching Quads in the Hall A line

(Fig. 1)
eDT shows some quads off design

Hall A delivery pocedure did not mention these matching quads

Spoke with Optics on call and they advised to take 1000 out of MQR1C19.BDL
