When the Earth-shadow deficit D = 1 − f_obs/f_control is recomputed on the complete 107,875-row VASCO working catalog for assumed shell altitudes of 20,000–60,000 km, the deficit is largest at an assumed altitude of 25,000 km (D ≈ 0.57) rather than at geosynchronous altitude.

Modelling preprint: global shadow deficit recomputed across assumed altitudes, largest at 25,000 km

what the source states

The source recomputes the Earth-shadow deficit D = 1 − f_obs/f_control on the full 107,875-row catalog for assumed altitudes from 20,000 to 60,000 km (Table 1) and reports it significant at all altitudes, with the "largest and formally most significant deficit occurring at an assumed altitude" of 25,000 km (complete sample D = 0.573 ± 0.031; GSO D = 0.517 ± 0.054).

what we infer

Same catalog, same group, same earthshadow code as TRN-E010/E011's subject matter; this is a re-analysis of the contested rows, not an independent extraction. The deficit values here (~0.5) are defined differently from the '~30%' the same source quotes in its introduction (p. 3) and from the 0.46% vs 1.4% figures in TRN-C005; the magnitude of the deficit is therefore definition-dependent and should not be compared across papers without the formula. Watters' non-uniform-background objection (TRN-E011) is not addressed by this table.

limitations

• Working catalog only; not an independently extracted candidate list
• Deficit definition and control sample (100 random points per plate on 635 plates) are the group's own
• The source does not engage the background non-uniformity critique of TRN-E011
