## Catalogue data

### WHAT KIND OF THING IT IS

What the object is in itself, rather than how it happens to look from here.

| Field | Value |
| --- | --- |
| Surface magnetic field | 1.22×10¹² G |
| Spin period | 1.9969 s |
| Spin-down rate | 7.3×10⁻¹⁶ s/s |
| Characteristic age | 4.33×10⁷ yr |
| Spin-down luminosity | 3.62×10³⁰ erg/s |

### WHERE IT IS AND HOW IT MOVES

Position, motion across the sky and the size it covers on it. These are measurements of the object as seen from here, so every one of them depends on where here is.
