Measured effects reported in the paper
| What was changed | Where | Measured | Effect |
|---|---|---|---|
| Use CHIRP instead of CLEAN | VLBI image reconstruction · Synthetic EHT measurements | image sharpness | Helped |
| Use CHIRP instead of SQUEEZE or BSMEM | VLBI image reconstruction · Synthetic sources, including extended and natural images | reconstruction quality | Helped |
| Use CHIRP across varying total flux densities | VLBI image reconstruction · Synthetic EHT measurements at different noise levels | noise robustness | Helped |
| Use a natural-image, celestial-image, or synthetic-black-hole patch prior | CHIRP · Synthetic EHT measurements | reconstructed image | No clear effect |
| Use CHIRP instead of the BU group's interactive calibration procedure | Real VLBI reconstruction · OJ287 | image sharpness and source resolution | Helped |
| Represent the image with continuous triangle pulses rather than discretized point sources (ablation) | CHIRP · VLBI frequency modeling | frequency modeling accuracy | Helped |
