(Duplicate of https://github.com/GalSim-developers/GalSim/pull/1273 due to rebasing/etc.) This pull request addresses https://github.com/GalSim-developers/GalSim/issues/1272 by defining a setter for the Image.array attribute. This protects against any case where a user does an inplace...

Image array throws error about having no setter but still performs operation

9

I guess this only works in an interactive session / debug shell, but modifying the underlying numpy array of an image _can_ be done despite an AttributeError being thrown. For...

Use NERSC DVS mount of Global?

2

Per https://docs.nersc.gov/performance/io/dvs/, it is probably preferred to access catalogs through `/dvs_ro` rather than `/global`. I believe this can be simply changed in the [site config](https://github.com/LSSTDESC/gcr-catalogs/blob/master/GCRCatalogs/site_config/site_rootdir.yaml#L1): ``` /dvs_ro/cfs/cdirs/lsst/shared ``` Note that...

[Python][Acero] Provide method to perform aggregations with acero for datasets

1

### Describe the enhancement requested Presently, `Dataset` has methods to perform several actions—`sort_by`, `join`, and `join_asof`—with Acero. It would be especially helpful to provide a method to perform aggregations on...

Allow independent handling of noshear in metacal

10

Proposed solution for #250. Rather than forcing the processing of `1p` if `noshear` is specified, this updates the code to check 1. if _only_ `noshear` is requested, then process that...

Metadetect won't run on only `noshear`

1

I was trying to do some quick metadetect tests in which _only_ the `noshear` step is processed. However, when specifying this in the config, metadetect keeps processing both `noshear` and...

Currently, GalSim will throw an error if the requested FFT is too large (cf. https://github.com/GalSim-developers/GalSim/blob/4c04a1ea4aa4c652c25019c0c7b5881f7571035f/galsim/gsobject.py#L1970-L1971). The default value for this is quite low (something like 2GB) and this often results...

Update I/O for parquet/etc. using pyarrow

1

I implemented a `Reader` that leverages pyarrow datasets. There are a few benefits to this: - More direct handling of parquet files than with pandas - Potential support for files...
