- Expand README with v03r00 data source instructions, ordering constraints, and full section I documenting the empirical Bolfac/Bolspot -> legacy Mg/SB conversion approach - Fix ancilliary -> ancillary typo and other minor typos - Restore ops DATADIR/OUTDIR as default in TSI_Mg_SB_merged_from_daily.py; keep personal paths as commented reference

Closes #72
NRL released v03r00 of the NRLSSI2 ancillary text files, which replace the legacy
sunspot_darkening_function/facular_brightening_functioncolumns withBolfacandBolspot. The v02r01 files are no longer updated past 2023.Changes
Mg_SB_from_daily_file.py: Updated to detect v03r00 files and convert to legacy Mg/SB format via an empirical least-squares linear mapping learned from the v02/v03 overlap period (1882–2023)TSI_Mg_SB_merged_from_daily.py: Updated plotting to shade the post-2024 v03-derived region; restore ops DATADIR/OUTDIR as defaultREADME.md: Substantially expanded with v03r00 download instructions, ordering constraints, and full documentation of the conversion approach including fitted coefficients and caveatsConversion approach
Since there is no official first-principles formula to convert v03 quantities to legacy units, an empirical linear fit is used over the overlapping historical period (1882–2023):
The SB mapping is very tight (R²=0.994); the Mg mapping has more scatter (R²=0.905) and post-2023 Mg values should be understood as approximations.
