This is a preprocessed ex vivo Langendorff rat whole-heart VF optical-mapping recording under 80 nM rotigaptide, recorded at 1000 Hz according to the deposit; that agrees with the value already on record. The 128 × 80 deposited image size matches both the deposit and the linked paper, and the paper also reports 1000 frames/s. The data have documented preprocessing before deposit, including background subtraction, 3 × 3 spatial binning, 100 Hz low-pass filtering, drift removal, and normalization, so analyses should not treat them as raw camera counts. Measured polarity is consistently non-inverted even though RH237 normally dims on depolarization, so use measured polarity for orientation. No acquisition-log or detected event annotations are available for this recording.

Inspector report 2026-10-27 20:27 UTC, model openai:gpt-5.5, provisional. Median per-pixel SNR over tissue is 18.818067017408147, with p10 = 13.893293967898506 and p90 = 25.936276941781777 over 3000 frames. The SNR tool cautions that temporal smoothing underestimates noise and inflates SNR; that caveat applies because low-pass filtering is documented and temporal smoothing was detected. The tissue mask contains 5216 pixels out of 10240 total pixels, coverage 0.509375. The mask source is a depositor NaN mask in frame 0; frame 0 has 5024 NaN pixels. No stored events were returned, no acquisition log is present, and no detected light transitions or image baseline-step events were returned. Therefore there are no event frames to interpret for this recording. If events are later added, image-only baseline steps should be treated only as fluorescence changes unless a log shows a light transition at the same frame. The tissue-mean slow baseline, measured with a 381-frame running median, changes from 0.4981755316257477 to 0.48741528391838074, a change of -0.010760247707366943, equal to -0.09788043294092134 of the p5–p95 beat amplitude. Slow baseline range is 0.1622154712677002 and Spearman trend is -0.3557674750723145. Because the deposit documents drift removal and normalization, residual bleaching cannot be separated from preprocessing effects here.
