A summary of work I've done at the Space Telescope Institute.

Bondage

I spent the day trying to understand the cdrizzle code.

Released

I created releas 1.0.2 of stsci_sphere and returned to looking at (but not yet doing anything about) the drizzle source code.

Not Yet Done

I spent the day making and testing the release of stsci_sphere

Towards the Finish Line

I found the remaining bugs in the stsci_sphere package and tagged it as release 1.0.1.  I studied the drizzlepac code some more. The function that seems to be the nub of the issue is map_value in cdrizzlemap.c

Two Projects

In the morning I studied the drizzlepac code. In the afternoon I got the stsci_sphere package ready for its public release.

This and That

With Mike's help I resolved the last issue with the sphere package. I started writing down my ideas on the WCS interface and checked out the drizzlepac code, with an eye to refactoring it.

Study Time

I spent the day reviewing the WCS code with an eye to completing the region handling code.

Study Time

I realized the test for the yaml code were wrong and fixed them by adding a new comparison method that handles complex objects. I studied the wcs code to bring myself up to speed for some new work.

Yaml Done

I finished work on the yaml fits extension, at least until someone else finds a problem with it.

Yaml No

I had second thoughts about how I am going to handle yaml and back the code out, writing some to a new, not yet version controlled file. I added code to register the new extension automatically and generate the data for the extension info output. I added a test for rewriting the extension data. It currently truncates the changed data to the length of the old data, which soulnds like a bug.
