Observed spectral lines

Input a comma-separated list of the observed spectral line frequencies [GHz], then click "Plot"

Settings

Frequency match distance The cutoff distance at which two redshift values are considered a match.

Figure width (pixels) Figure height (pixels)

Figure size parameters (set width = -1 for automatic).

Redshift down Redshift up

Lower- and upper-redshift bounds on the figure. Number of CO lines The number of CO lines you wish to plot. Frequency padding The frequency difference [GHz] to use as margin for the y-axis above and below max and min observed spectral lines.
