• Replacing the IDL AstroLIB functions?
• Jython
• Building a replacement for numpy
• Not compatible with numpy
• Use JNI to pull C components of numpy into Jython?
• JNI is platform dependent
• JNI code would be hard to distribute
• Jython projects "need" to be
  

• We have already switched from numarray to numpy
• Booklet on doing the conversion
• Data analysis tutorial has been updated to use numpy
• Need a numpy reference that is more than a tutorial but less than Travis' book
• Need to make our internal documentation more consistent
• Need a reference document for our products
• Need a matplotlib cookbook geared for astronomers
• simple "how-tos" for generating plots
• common examples and some offbeat things that are hard to figure out
• Making publication quality plots
  

• Spitzer Software
• Possible replacement for IRAF?
• Very generic
• Not compatible with existing IRAF tasks
• Is anyone interested in helping out?
• Written in Python
  
• Think of it as an IDE for data reduction
• Based upon IRAS extraction routines
• Current system has a plugin architecture
• Licensed under the GPL
• Everything is in Python
• Uses qt and pyqt for interface code
• All file management is done internally
• Ideally you would only need a basic knowledge of the framework
• No work has been done on the photometric side of things
• Currently operates for spectral extraction
• Comments
• Quick look niche application?
• Not likely used for publication quality data reductions?
• Thing to do would be to put it out there and see who uses it
• Currently not very public
  

•  How to communicate to astronomy community?
• Astropy?
• not high traffic -- STScI's fault
• more of a developer list
  
• Scipy, numpy list
• sci.astro the group
• used by observers
  

•  Performance Issues
• Tables
• Header Manipulations
  
• Added features
• streaming data mode
• code has been reorganized
• allows for STScI conventions
• Read FITS files given a URL
• Can read zipped files
  
• Support for compressed extensions
  
• Interested in parallel computing
• Could pyfits read and write to streams?
• we would need to look into it
  
• Some scaling cases we don't return the correct "type" for the object
• int32 to float32 will lose person precision
• we will likely just return a higher precision
• VOTable support

•  Driven by Gemini
• Currently fixing bugs and adding features
• Remove the dependence on IRAF
• Add matplotlib as a graphics interface

• We pull things out of scipy so that we don't have such a large dependency
• Fix the installation issues
• eggs?
• The numarray packages now live under scipy
• ndimage
• image
• convolve
• We can add some of the functionality that lives in IDL to scipy
• For scipy 1.0 release
• need docs
• distribution issue
• installation of individual packages

•  we are actively working on fixing holes we have found
• math text
• memory leaks in GUIs
• distribution issues
• needs to be easier
• bundle dependent libraries?
• zilb, freetype
• make setup smarter
• Is there a way to fix an image size easily?
• Yes
• try fig image
• raw pixel dump
• no interpolation
• Make heavier use of traits?
• Changes to backend modules?
• Merge with Chaco?
• If serious refactoring of internals then the object interface will likely break.  The pylab interface should remain the same.

•  STScI wants to do more work
• done coordinate work
• Someone posted a wrap for WCS support
• Working on a python approach to synphot
• on astrolib svn but not advertised
• Activity from STScI should pick up again
• Some people interested in doing literal translations of IDL aston utilities

• Replacing IRAF tasks with Python versions
• Photometric packages
• daophot
• apphot
• Take current ongoing projects and make them Python friendly
• would not be rewrites
• What is going to replace IRAF?
• Parallel processing
• How can we use multicore processors that is not too onerous
• it seems easy to run Python tasks as separate processes
• memory mapping as a way of sharing memory?
• Threads can't alter reference counts arbitrarily
• Global Interpretor Lock allows only one thread to run at a time
• Is there going to be a replacement to skycat?
• All replacements seem to have gone unsupported
• There is a need for something that fills skycat's role
