@sophiejaggers.bsky.socialAnother way to measure stellar parameters is to compare predicted and observed pulsations.
But how can we tell whether the frequency we observe is a single oscillation mode, and not a mixture of several unresolved modes?

@hydezero-message.bsky.socialPaid guide to Atira: work through slit losses, absorption baselines, error propagation and future observations. Teaching examples: band depth is not water content, and surface-to-interior inference needs assumptions.

@dan-pelliccia.bsky.social📈 Here's a few more thoughts and tips on regularised least squares for spectral smoothing.
This is written for #NIR and #optical #spectroscopy, but the general idea is just as applicable to other types of signals.
