Add Quantity as a valid value_type in config

1

There are a few places in GalSim where we have unit-ful values as parameters to various things, which are documented to assume a particular unit. (E.g. our wavelengths are all...

Currently SEDs are much faster if their underlying function (`spec`) uses a LookupTable with `interpolation='linear'`. When this is the case, various manipulations preserve the function tabulation (e.g. multiplying by a...

HIERARCH + CONTINUE doesn't work.

2

fitsio can read/write long value items into a header using CONTINUE lines. And it can read/write long keyword names with HIERARCH lines. However, combining the two fails. Here is a...

Add the first composite type: Sum

4

This is finally the first composite type that I've been working up to. Sum is probably a little simpler than Convolve, so I wanted to start with that. But the...

@aguinot mentioned to me today that he has a use case where the weight map is not a separate hdu of the image file, but rather its own file. I...

Now that we have non-trivial star selection included in Piff, there are use cases where people might just want to run that without doing the subsequent PSF modeling. I think...

Delay read of instcat until data is needed

2

Address #464 take two. I removed the approx_nobject keyword, and now implement getApproxNObjects() by just counting the lines in the instance catalog file. This will always be >= the number...

Apply DCR for faint objects

1

@esheldon discovered a bug in our rendering of very faint objects. We currently skip over the photon ops if the flux is < 100 photons. This is mostly fine, since...

Fringing pattern not deterministic

2

Apparently the Python hash function is not deterministic as of Python 3.2. This is for good security-related reasons for most typical kinds of applications of hashes. But it means our...

Invalidate checkpoint files when config dict changes

1

The docs have this warning currenty: ``` .. warning:: Be careful to manually delete any check-point files if you have made any changes to to the configuration between runs. Currently,...
