Instructor key. Numeric values are generated by build_astr476_package.py from the computation module and the included source subset.
Solution 1
For the 18-row excerpt, beta=-0.119973 +/- 0.040168 mag; chi-square fixed=28.2200, after GLS intercept=19.2993.
Solution 2
The excerpt is deliberately stratified, only 18 rows, lacks the full 1701x1701 survey likelihood and selection model; intercept was fit at fixed shape and is not Omega_m/H0 inference.
Solution 3
Read exact fields from the selected published summary row; use reference-log.md for source key, model label, date, and Level 1 versus Level 2 classification.
Solution 4
Need full source likelihood/data, within-probe covariance, cross-probe covariance/shared calibration, harmonized parameterization and priors, nuisance models, and validated selection functions.
