What would be nice would be a calculator (for example "Illuminance" on the "Star" sheet) that could say how much of the star's energy output is in a specific frequency...

Nice, I would also test in Google Docs and Excel Online because not all OpenDocument features are 100% compatible between the three. But those are details that can be debugged....

Here are some resources that may be helpful in modeling a H₂O and CO₂ based greenhouse effect on rocky planets, as well as possible ranges for a circumstellar habitable zone...

Thank you for your effort. I had a look at the sources soon after you posted them and they are really useful in respect to the relative contribution of various...

This is in respect to the equator of Earth. I already found some formulas: [Conversion of coordinates ](https://www.atnf.csiro.au/people/Tobias.Westmeier/tools_coords.php). Also see Google search ["equatorial to galactic coordinates formula"](https://www.google.com/search?q=equatorial+to+galactic+coordinates+formula). Such a calculator...

I would standardize on degrees and include a degree radian converter on the "Conversion" sheet.

I am in the process of finally implementing the calculator but my math skills are not that great in the trigonometry and equations areas. After some tinkering I got the...

It is 3.2.1 but the principle is the same. Yes, I already use ARCSIN/ARCCOS as the inverse operation before I convert to degrees. The issue is the `l - l0`...

It is on "Conversion", the purple one. Fifth calculator from the top.

I linked a work copy of the sheet in a previous issue comment. https://github.com/lortordermur/sfcalcsheet/issues/5#issuecomment-2289237342
