[TICA data products](https://archive.stsci.edu/hlsp/tica) are now provided ahead of other official TESS data releases under a pilot program that started yesterday. How could these products be read with lightkurve? We used...
A seemingly unjustified `true_divide` warning message pops up when normalizing a spectrum: ```python import warnings import astropy import numpy as np import astropy.units as u import specutils # See Issue...
Hi astroplan team! Thanks for making a great software. I made a tutorial about how to use astroplan with custom constraints for the Hobby Eberly Telescope's fixed elevation design. Is...
_The problem:_ Not all residual spectrum outliers originate solely from line strength mismatches. In general, line _width_ mismatches or line center shifts will be present in the residual spectrum as...
Version 0.2 is out, so version 0.3 roadmap is here. :rocket: Simple goals for this release: - [x] Air/vacuum instrument class support #57 - [ ] Enhanced terminal output during...
## Priors on stellar parameters _The problem:_ I suspect that a common use case might resemble the following scenario: A user would like to force the value of a parameter...
I am adding a new module to support inferences of an emission component from circumstellar disks. My assumptions for the purpose of this implementation are: 1. The emission component is...
At (sufficiently) high spectral resolution, and with (sufficiently) rapidly rotating stars, the line broadening can be dominated by the (projected) rotational broadening, often parameterized by vsini. At low spectral resolution,...
Starfish currently supports calibration polynomials in the flux domain, parameterized as Chebyshev polynomials (c.f. Czekala et al. 2015). In principle there could be calibration uncertainties attributable to *wavelength-domain* instrumental artifacts--...
Hi folks, I recently emailed some Starfish quick start notes to a colleague, and thought I'd post them here in case they are useful to anyone else. More tips/tricks for...
