## Where it stands

**Disputed** None pieces of evidence for, two against. It needs two reviews to be accepted.

## What it predicts

- Independent re-fits with other weighting or data selections remove the signal.
- A photocentre offset or systematic error in the Hubble positions explains the residuals.

## What would rule it out

- An independent re-fit that confirms the acceleration at high significance.
