⚠️ Library-first merge gate

Merge PyAutoLabs/PyAutoArray#547 first. This PR forwards a keyword that only exists on autoarray.plot.plot_array once that PR lands; against an older autoarray it raises TypeError: plot_array() got an unexpected keyword argument — but only when a caller actually passes arcsec_after_decimal, since the default is None and it is forwarded unconditionally.

Summary

autogalaxy.util.plot_utils.plot_array wraps autoarray.plot.plot_array with an explicit keyword signature and no **kwargs, so it has to name a parameter in order to pass it on. This adds arcsec_after_decimal and forwards it.

That wrapper is also what autolens.plot re-exports (autolens/plot/__init__.py:12 imports plot_array from autogalaxy.util.plot_utils), so this one-line forward is what makes the originating request's acceptance criterion — aplt.plot_array(array=array, arcsec_after_decimal=True) — work for both galaxy and lens users. PyAutoLens itself needs no change.

API Changes

autogalaxy.util.plot_utils.plot_array gains one optional trailing keyword, arcsec_after_decimal=None, forwarded verbatim to autoarray.plot.plot_array. True places the arcsecond ″ over the decimal point (3.″8), False forces the suffix form (3.8"), None (the default) reads the ticks.symbol_over_decimal config flag.

Purely additive and appended last, so no positional call site is affected and default behaviour is unchanged.

See full details below.

Test Plan

• Related plot tests (test_plot_array_mask.py, test_plot_norm.py, mat_wrap/test_visuals.py) → 22 passed, run against the branch checkout of PyAutoArray
• End-to-end through this wrapper on a 10×10 Array2D, reading tick labels back off the axes: True → ['-1.″9', '0.″0', '1.″9']; None and False → ['-1.9"', '0.0"', '1.9"']; the PNG is written in all three cases
• Re-export reachability confirmed: aplt.plot_array is plot_utils.plot_array → True, and the signature carries arcsec_after_decimal → True

Heart gate: pyauto-heart is not reachable from this remote session, so the documented fallback (per-repo pytest as the gate) was used — see the counts above.

Full API Changes (for automation & release notes)

Added

• autogalaxy.util.plot_utils.plot_array(..., arcsec_after_decimal=None) — forwards the per-call arcsecond tick-label override to autoarray.plot.plot_array. Also reaches lens users unchanged via the autolens.plot re-export.

Removed

• Nothing.

Migration

• None required — every existing call site keeps its current behaviour.
• Before (per-figure override): mutate conf.instance[...]["ticks"]["symbol_over_decimal"], then restore it
• After: aplt.plot_array(array=array, arcsec_after_decimal=True)
