Phase1 Full Freeze v2 — 执行状态 (2026-08-08)

控制包: AstroCS_Phase1_Full_Freeze_v2_PSF_DR3SP_Oracles.zip (SHA256 5da02b0a3b42949ee3452fb913783712b1e3ec0b7bc72e40ddf85ac38cca5c49)

修订流水线 (已实现并验证)

CALIBRATE -> PSF/STAR_MEASURE -> PLATESOLVE -> PHOTOMETRIC -> SNR
  • PSF 阶段: 单次权威检测 + PSF 拟合 + stable star_id (star_det FLOAT64[N,6] + star_measurements FLOAT64[N,15])
  • PLATESOLVE: 消费 PSF star_det (ipv_solve_from_detections_v1), 禁止重检测
  • PHOTOMETRIC: per-star photometric_match 块 (star_id/dr3sp_id/ reference_flux/residual/status/reason), 复用 PSF instrumental flux
  • SNR: 复用 PSF 测量, 无第二套检测

Gate 结果

Gate 结果
4 DR3SP/GaiaXPy PASS: 1050 星×G/BP/RP, 逐带 p95
2 PSF Photutils PASS (收敛初始化 0.004px) + BLOCKER PSF-001
3 WCS Astropy PASS: 往返 3e-11px (astrometry.net 未安装)
7 HiPS PASS: AIO 唯一写入, 24 tiles + MOC + properties (astropy 独立读取)
8 实际 buffer trace PASS: 9 阶段 manifest, star_id loss=0/mutation=0
10 真实数据 T2/T3 → NSIDE 65536, T4 crop FP32/FP64 → hiss_verify

BLOCKER PSF-001 (阻止彻底冻结)

DPSF 质心收敛不稳定: 以 sdet 像素中心坐标为初始时 LM 收敛到整数像素 (~0.5px 偏差); 以整数为初始则精确收敛 (<=0.01px)。生产路径受影响, 按修改预算不修改冻结 PSF 数学, 需单独 BLOCKER 修复周期 + 模块回归。

状态

Phase1 科学核心通过 / 数据流与精度契约继续验证
HISS=DEPRECATED (保留兼容) / HiPS=迁移完成待外部工具验证

最终完整 FP32 单帧未运行 (PSF-001 未闭合, pre_full_run_gate 不满足)。
