The temporal analogue of a PSF convolution: a detector's timing uncertainty (SPAD jitter + TDC quantisation + laser pulse width) smears every arrival time by the instrument response function, here a Gaussian of full width at half maximum *irf_fwhm_ps*. The kernel is the exact bin integral of that Gaussian (erf differences), normalised to sum 1, truncated at +-truncate*sigma and forced to odd length so the convolution is centred.
Ground truth: convolving a unit spike in the middle of a 256-bin window with irf_fwhm_ps = 500 at bin_ps = 50 leaves the centroid exactly where it was (measured shift 0.0 ps — the kernel is symmetric) and gives a profile whose measured FWHM is 501.22 ps. That 0.24% excess over 500 is the *measurement*, not the kernel: tcspc_stats finds the half-maximum crossings by linear interpolation between bins, which slightly overestimates the width of a Gaussian.
Total counts are preserved *except* at the window edges, where mode='same' discards the tail that falls outside — measured loss exactly 0 for that centred spike, but a genuine loss for a pulse within a few sigma of either end.
Returns a float64 1-D histogram of the same length as *hist*.
Raises ValueError: negative, non-finite or non-1-D *hist*, a non-positive *bin_ps* / *irf_fwhm_ps* / *truncate*, an IRF sigma below 1e-3 bins (the kernel would be a delta and the op a no-op — say so instead of pretending to blur), and a kernel that would be longer than the MAX_BINS cap.
