Natal Psyche → Scutum
42.276°
Psyche 240° on the local dial. HI peak step 42.276° (family 42.28° Δλ). Andromeda null. 1420 MHz line is the radio, not the angle.
Natal. Hydrogen is the first element. Its radio line is a real beacon. Cluster is more interesting than one lonely hit. Living pattern, labeled as pattern. Name the invitation without demanding the whole universe agree.
What it supports
Scribe Psyche 240° against ridge 282.28° prints 42.276° (Δλ ~42.28°). Great-circle sky angle is wider (~46.07°). The 21 cm line is 1420.405 MHz.
What it does not
Not a lab pin on HI4PI until (ℓ, b) is re-checked. Not the natal lamp. Not Psyche → Sun. Not four extra 42s from a 41° band.
Calculation
282.28° − 240.00° = 42.28° (Book print 42.276°)
Book-table subtraction on Psyche longitude; not a new (ℓ, b) reduction
