Light curve

Observed magnitude by reported observation time. Axis labels identify the displayed time and magnitude systems; brighter measurements appear at the top.

Chart data loads when this section becomes visible.

Spectrum

Compare up to 10 selected full-resolution observed spectra on one chart. Raw flux is shown by default; normalization is an explicit display option.

Spectrum choices load when this section becomes visible.

Move across the chart to inspect the nearest point in each selected spectrum.
Flux display Normalization divides each spectrum by its maximum absolute reported flux.
