While debugging #7328, I discovered that some of our test FITS files cannot be read after updating their header WCS. Here's a minimal example, where I don't even make any changes to the WCS:

Dear all
I needed to add a gaussian component to my background. With the help of @thomasaarholt I made some progress but see the following

## Reason
Integration of harmonic, or quasi-harmonic, acceleration or velocity time histories can result in displacements that exhibit an unrealistic deviation from a particle's initial position over…

We have not been proficient at documenting the estimated runtime or space complexity of our estimators and algorithms. Even were we to document asymptotic complexity functions, it would not give a rea…

In the `_calc_nf` method in the EDFA class, for the advanced model, the average NF is evaluated from target gain and polynomial coefficients like this:
`nf_avg = polyval(self.params.nf_fit_coeff, -…

The principle of how gradient descent works makes sense, but it still relies on calculating a "gradient" at any point. When there's a closed form representation as a function, this is doable, but what…

GCD for polynomials is an important operation for computing sums of polynomial ratios A(x)/B(x) + C(x)/D(x). The naive approach to computing GCD(B(x),D(x)) is numerically ill-conditioned:

Deer professor and peers
I did a google search and I got that we are able to find quadratic model of two variables using lm(y~poly(x,2)).
I tested lm( y~ poly(x,1)) and I found that the result i…

We want pyspeckit to use specutils (specutils.rtfd.org) for as much of the underlying machinery (e.g., file io) as possible. This requires a plan, which we need to develop here first.
We want a map …
