This video shows the "pollution" of the CaH line with the H-epsilon line. It's an animation at +-3Å from the center of the CaH line. It clearly shows the filaments reappearing at 3970Å, at the position of the H-epsilon line! https://www.you
What “spectrography” means

every network with a public tag surfaceFollow #spectrography straight to each platform’s own tag page. Where a platform publishes open data we measure it above; the rest lock their numbers behind paid APIs, so we link rather than guess.
Every number above is measured from a named public API at the shown fetch time. Nothing is estimated or extrapolated. Platforms that lock their data behind paid APIs are not shown. Agents: the same numbers, as JSON, at /api/hashtags/spectrography
