Peter and Frank,
FWIW, I am using Meeus' formulas and the J2000 positions and proper motions from the FK5 catalogue. I cross-checked my spreadsheet with a few instances in the 2022 NA and saw a maximum difference of 0.2' in SHA for R. Kent. and 0.1' for Sirius.
I have attached an unlocked version of my spreadsheet for reference. But apparently you can open all of the tabs with LibreOffice anyway - even with the password protection. >:(
Right-click one of the tabs and select "Unhide" to show the hidden sheets. And please excuse the mess ... not all of it was meant to be seen.
