From f6e76e08ae670730508c83e485a7906d96fa2731 Mon Sep 17 00:00:00 2001 From: Theodore Kisner Date: Mon, 23 Feb 2026 07:52:52 -0800 Subject: [PATCH 1/2] Changes needed to work with new so3g These changes are designed to allow sotodlib to pass unit tests with both the legacy so3g / spt3g as well as current spt3g plus the in-development version of so3g which uses pybind11 instead of boost. This PR just enables the passing of unit tests, which do not test the creation and loading of books. In particular, the book binding code and all other uses of G3SuperTimestream need to be updated before we can use the new so3g. --- sotodlib/coords/demod.py | 26 ++++++++++++------------ sotodlib/coords/helpers.py | 23 +++++++++++++++------ sotodlib/core/g3_core.py | 41 ++++++++++++++++++++------------------ sotodlib/g3_condition.py | 13 +++++++++--- tests/test_coords.py | 17 ++++++++++++---- tests/test_demod_map.py | 9 ++++----- tests/test_toast_books.py | 6 ++++++ 7 files changed, 85 insertions(+), 50 deletions(-) diff --git a/sotodlib/coords/demod.py b/sotodlib/coords/demod.py index 396fd64ef..fa6803464 100644 --- a/sotodlib/coords/demod.py +++ b/sotodlib/coords/demod.py @@ -41,7 +41,7 @@ def make_map(tod, If specified, trim source-centored map to a local square with `size`, in radian.
