But you do learn from such things (opening a file, reading from the network). All the stuff that can go wrong, and that it all has to be handled. Like writing a device driver. It’s useful to write that C code, and then try to break it (e.g.

Pixelmator Pro is great. I was just an occasional Photoshop user, so its subscription model was a poor fit. So I hopped off Photoshop some years ago with much relief.

Excellent point. The unit conversions in OP are all in astropy, as well as projections into the many possible coordinate systems. Another resource is the star/exoplanet catalogs at ( https://exoplanetarchive.ipac.caltech.edu&

Yeah, but CH4 detection was not why the mission was flown, so the PI is being careful to make this distinction.

Several questions ask to contextualize this measurement. Here's a highly-cited paper in Nature (including some of the researchers quoted in the OP) that describes how an earlier survey of California methane emissions went: https:&#x

You seem to be writing to correct the commenter above, but in fact the commenter is correct. Because the M scale is logarithmic, you need a lot of M5's to release energy equivalent to an M6. So, the M5's aren't helping to s
