astroimtools's Issues

Migrate functions to other repos and retire this one?

I still feel like we don't actually need this as its own standalone repo. The convenience functions here can be more exposed and better maintained upstream in the relevant repos (e.g., astropy, photutils, ccdproc, etc).

Use Lupton RGB in Astropy 1.3

After Astropy 1.3 is released:

  • Remove the Lupton RGB function from this package.
  • Use Lupton RGB function from astropy.visualization in notebook example.

Demo ideas (Sprint acceptance checklist)

Here are some items to consider for the sprint demo:

Ring filters

  • List of commonly-used filters available in astropy and scipy
  • Generic creation of a filter footprint
  • Ring median filter
  • Annular median filter
  • Filter when data is in an NDData structure
  • Filter when there are NaNs
  • Options for different treatment of the image boundaries (or mask boundaries?)
  • [ ](Filter when there is a mask)

PSF Convolution

  • FFT Convolution with a JWST PSF
  • Convolution with even- and odd-dimensioned kernels (discussion of the image shifts)
  • Convolution performance
  • Astropy documentation enhancements & astropy tutorial
  • FFT convolve data with NaNs or a mask?
  • FFT convolve when data and PSF are in an NDData structure

Inverse-distance-weighting (IDW) interpolation

  • Example use case: fitting sky background on a masked image
  • Comparison to other interpolations on the same image

Adding a custom filter to astropy

  • ipython notebook tutorial demonstrating this

listpix output labeling

I think it might be better to label the output "col' and "row" in the table rather than "x" and "y", just to help encourage people to think that way, especially since the input parameters are in (row,col) order.

Infrastructure updates notice from Astropy Project

Hello from Astropy Project!

The following updates to your package might be necessary to ensure compatibility with the latest stable version of Astropy:

  • MPLBACKEND is now set to Agg in ci-helpers, packages expecting interactive plotting should override it in .travis.yml
  • Astropy 3.1 is not compatible with Numpy <1.13 versions. If you want to keep testing these older Numpy versions, please use ASTROPY_VERSION=3.0 or ASTROPY_VERSION=LTS in your Travis CI matrix.
  • Add sphinx-astropy as a package dependency if you are using astropy-helpers 3.1 or later. Otherwise, your documentation build (e.g., on ReadTheDocs) might fail.
  • If you are using six that is bundled with Astropy, please consider using the standalone six package instead.

If these are no longer applicable to you, please close the issue.

This is an automated issue for packages that opted in for automated astropy-helpers update. If this is opened in error, please let @pllim know.

xref astropy/astropy-tools#108

Update the help

Tyler Desjardins mentions that we should consider moving emails from help[at]stsci.edu to point to the web portal where possible and appropriate. For HST (or any non-JWST), it is https://hsthelp.stsci.edu . For JWST, it is https://jwsthelp.stsci.edu . Please update info in setup.py, setup.cfg, documentation, etc as appropriate.

Please close this issue if it is irrelevant to your repository. This is an automated issue. If this is opened in error, please let pllim know!

xref spacetelescope/hstcal#317

Retire Python 2

Python 2 will not be maintained past Jan 1, 2020 (see https://pythonclock.org/). Please remove all Python 2 compatibility and move this package to Python 3 only.

For conda recipe (including astroconda-contrib), please include the following to prevent packaging it for Python 2 (https://conda.io/docs/user-guide/tasks/build-packages/define-metadata.html?preprocessing-selectors#skipping-builds):

build: 
  skip: true  # [py2k] 

Please close this issue if it is irrelevant to your repository. This is an automated issue. If this is opened in error, please let pllim know!

Update RTD domain name

Change all references of readthedocs.org to readthedocs.io. This is not urgent but should happen eventually.
