The scripts that processed the NGC 5128 session of 2026-07-21 previously
lived inside the data directory and addressed it with absolute paths.
Code and data are now separated: the code lives here, and a session is
located at runtime through the ASTRO_SESSION environment variable.
layout.py is what makes that work. It maps a FILENAME to the
subdirectory that file belongs in, using the same rules the session
directories are organised with, so a script can go on asking for
'master-Red.fit' or '_stars.npz' without any call site knowing the
directory structure. Anything unrecognised resolves to the session root,
which is visible and correctable rather than silently wrong.
restructure.py reorganises a flat session directory into that layout. It
is idempotent and dry-run by default.
The 50 session scripts are kept as they were run rather than tidied into
a library. They were written in sequence as the work went along, several
of them by parallel agents, and they show it - but they are the honest
provenance of a published set of results, and the productionised pipeline
should be able to reproduce those results exactly.
Verified before committing: all 51 files compile without warnings, and
verify_core.py, closeup.py and triptych.py were run end to end against
the reorganised session, correctly finding inputs across calibrated/,
stacks/masters/ and final/ and writing outputs back to the right places.
Repo created for a reference/review of the iTelescope.net remote telescope
network. This commit copies the Default Workflow in (CLAUDE.md and docs/ from
the Default-Workflow repo), adds a .gitignore (secrets and scratch), and fills
in state/PROJECT.md with the objective: review every telescope on the network
and provide a choosing guide, using only public sources (support article and
the maintained Google Sheet; the go.itelescope.net launchpad is login-only).
