Hello!
I follow the usage of pyspecnest to fit the ammonia spectral line with two velocity components. The interval of two velocity components ranges from 0.6 km/s to 3km /s. I use the script to sam…

CO immediately comes to mind, but maybe OH 1667/1665 as well.

Users should be able to select particular spectral lines for their observations based on the spectral windows they define. Those lines (and accompanying meta-data) should come from an online catalogue…

Dear all,
Using the equivalent widths, I must calculate the chemical abundances for different spectral lines to derive the stellar parameters. In previous versions of Turbospectrum, I used to use t…

Hi,
Good to hear you are working on a new release.
Maybe this bug was already addressed.
I'm pre-processing using the default one-bit spectral whitening.
I decided to change the `window_durat…

Joshua Jost helped us identify two problems with the `line_list()` function.

I am using Cherab to model AXUV diodes which are sensitive in a very wide spectral range (from 1eV to 1keV+) and I would need a way to define logarithmically spaced spectral bins. Simply trying to set…

While reading through this code I stumbled upon these particular three lines of code.

```glsl

Some parts of the sky show substantial spatially variable nebular emission. e.g., this related ticket

This occasionally compromises redshifts when re…

**Context**
One of the key features of the spectral lines of the Sun is whether they show a strong _flash spectrum_. This is the realm of the chromosphere, prominences (hydrogen and calcium primarily…
