If you run the following modeling example:

And manually input an `add_assertion` in the `mod…

In PyAutoLens, we often compose a model where a galaxy is made of 90 Gaussian's:
```
analysis = al.AnalysisImaging(
dataset=dataset,
adapt_images=source_pix_results[0].adapt_…

I want to know if you use:
1. `mag/arcsec^2`/`mag/pixel^2` (with `-2.5log`)
2. `W/m^2/sr` (without `-2.5log`)
for $I(r)$ in Sersic profile:
$$
I(r) = I(0)\exp(r/r_0)^{1/4}
$$

I found another case where SE++ runs in circles doing nothing. The full dataset is available here (280MB):

The catch is the python config file asks for Sersic fit, but t…

We should try and add more mass models, e.g. the ones that appear in Nightingale et al. (2022) - "Scanning for DM subhalos..."

I fitted an elliptical galaxy using three series models and output a comprehensive best fit model.
I c…

When comparing the FastSpec stellar mass measurements to SDSS MPA-JHU I noticed a pretty large constant offset between the two measurements. Whether this is due to an issue or just the result of diffe…

For some reason when I run a simulation with background galaxies (as well as point sources), simulating the galaxies seems to be running at about 300 galaxies an hour. This seems significantly slower …
