Field Series 8 — Field 4426, NIRSpec G140M

jw04426 again, third observation, this time G140M with F100LP — the shortest wavelengths NIRSpec’s medium-resolution gratings reach, on the same field Episode 10 reads further into the infrared. Three movements as before: the hundred most distinctive passages over fourteen minutes, the open field for ninety-three, the fifty rarest over seven. The shift down in wavelength shows. Lines, brightness and gradient are near level at the top of the distinctive suite — three readings that all respond to spectral features directly — while holonomy, which was second in Episode 10, collapses to three passages out of a hundred. The rare suite follows the same logic: gradient first, lines second, and material drawn from all seven readings rather than piled into one. Two exposures of one field, and the grating decides what the field is made of. Before Birth is an acknowledged test series.
