Almanac spreadsheets in 2021


Comparisons with the 2021 Nautical Almanac Commercial Edition show that our spreadsheets remain sufficiently accurate for the year 2021 without the need for any changes or updates in the calculations.

Spreadsheets aries_stars.xls and what_star.xls were modified with the changed spelling of one star’s name (Alnair). Archive TAR and ZIP files were also updated accordingly.
