The serval-calculated activity indicators from our MAROON-X data. From the top to bottom panel, these are: the chromatic index in the red and blue channels, the differential line width in the both channels, the hydrogen alpha line index in both channels, the three calcium infrared triplet line indices (8500.4, 8544.4, and 8664.5 Å), and the two sodium doublet line indices (5891.6 and 5897.6 Å).
