Trying your examples, especially considering that the elliptical orbit of the earth likewise causes the Sun's angular diameter change depending on where our orbit is, I found that Units current has a buggy definition of moondist_min and moondist_max. It's defined in the definitions file as 356.371 km and 406.720 km respectively. These should be Mm! (Or remove the period, either will work)
Just to work around the bug, you can use a local definitions file to correct it:
cat > ~/.units <<EOF
moondist_min 356.371 Mm
moondist_max 406.720 Mm
EOF
- kragen 3y agointeresting, looks like an effort to improve the precision resulted in a factor of 1000 error! `help moondist_max` shows me considerably less precise values: sundist 1.0000010178 au # mean earth-sun distance moondist 3.844e8 m # mean earth-moon distance sundist_near 1.471e11 m # earth-sun distance at perihelion sundist_far 1.521e11 m # earth-sun distance at aphelion moondist_min 3.564e8 m # approximate least distance at # perigee 1901-2300 moondist_max 4.067e8 m # approximate greatest distance at # apogee 1901-2300
- chungy 3y agoWhere are you typing help to get that output?
- kragen 3y agoat the units prompt You have: help moondist_max then i scrolled up a few lines in less
- chungy 3y agoI could've sworn I tried and didn't get anything. Now it is working. I don't know what I did! (running version 2.22, at any rate)
