Tied [OII]7320/[OII]7330 flux ratio inverted #119

Closed dirkscholte closed 1 year ago

dirkscholte commented 1 year ago

The [OII]7320,7330 lines are tied such that amp([OII]7320) = 1.0 / 1.2251 * amp([OII]7330). This should be the other way around: amp([OII]7320) = 1.2251 * amp([OII]7330). This was correctly implemented PR #87 associated with issue #84 . However, likely during the refactoring of the emission line fitting this tied emission line ratio got switched around.

Small changes to be made in emlines.py and nebular-lines.ipynb to correct the inverted emission line ratio.
