Field Series 10 — Field 5086, NIRSpec G235H

The last of the Field Series: jw05086, first observation, NIRSpec G235H with F170LP — the same instrument configuration as Episode 7, a different programme and a different piece of sky. Fourteen minutes of the most distinctive passages, ninety-three minutes of the open field running brightness, obstruction, gradient and into lines, and seven minutes of the fifty rarest to finish. This cube is led by its spectral lines. More than a quarter of the distinctive suite comes from the line reading — continuum-subtracted brightness, where only the emission and absorption features remain — with raw brightness behind it. Flow is effectively absent, a single passage in a hundred, and contributes nothing to the rare suite. What is rare here is obstruction and anisotropy: disagreement between neighbouring spectra, and structure that runs one way rather than another. Before Birth is an acknowledged test series.
