v0.3.4 - Timedelta Error Calculation Fix (2025-12-22)¶

What Changed?¶

This release fixes a critical bug in the timedelta_us error calculation alignment. The correction ensures accurate error metrics when analyzing timing data from cosmic ray detection events. This maintenance fix maintains full backward compatibility with existing analysis workflows.

What's New¶

Bug Fix: Timedelta Error Calculation Alignment¶

What it does: Corrects the alignment of timedelta_us error calculations to ensure accurate timing error metrics. This fix addresses a calculation bug that was producing misaligned error values when analyzing timing data from cosmic ray detection events.

Impact: Users analyzing timing precision in detection event data will now get accurate error metrics that correctly reflect the measurement uncertainty in microsecond-level timing differences.
