AU / Physics model (minimal)

Constant solar irradiance at 1 AU: I₁ = 1360.8 W/m².
Solar irradiance at distance r (AU): I(r)=I₁/r².
Reflected-object magnitude model (minimal): m = H + 5·log10(r·Δ) + P(α).

r: Sun→Object (AU)

Δ: Object→Observer (AU)

Phase angle α (deg)

Phase strength (β, mag/deg)

AU anchor (600 AU baseline)

Baseline: I(600 AU) = 0.00378 W/m² (matches 1360.8/600²).
Scaling (inverse square): I(AU)=I(600)·(600/AU)²
Magnitude shift: Δm = -2.5·log10(I(AU)/I(600)) = -5·log10(600/AU)
Expected magnitude: m_exp(AU)=m600 + Δm

Color / Spectral (heuristic)

From RGB we estimate a pseudo B−V (log-ratio heuristic), then map to O..M. Optional color correction: m_corr = m + C·(B−V).

Object inspector (WISEA-style)

Select a detected track to view a compact “WISEA-like” analysis record. For true WISEA Jhhmmss.ss±ddmmss.s naming you need WCS/RA-Dec calibration; here we show a structured photometry+motion record.
