| Findings    | - Measure the size-luminosity relation of photometrically-selected galaxies within the redshift range of 6 to 9.                                                                                         |
|             | - Find steeper slopes of the size-luminosity relation for lensed galaxies compared to blank fields, and consistent with other independent determinations from the HFF dataset.                           |
|             | - Investigate the systematic uncertainties correlated with the choice of lens models, finding that the modeling errors are not a significant source of uncertainty.                                      |
| Methodology | - Use galaxies lensed by six foreground Hubble Frontier Fields (HFF) clusters.                                                                                                                           |
|             | - Obtain properties of sample galaxies from the photometrically-derived ASTRODEEP catalogues.                                                                                                            |
|             | - Measure intrinsic size with the Lenstruction software.                                                                                                                                                 |
|             | - Create completeness maps as a function of size and luminosity via the GLACiAR2 software.                                                                                                               |
|             | - Perform a Bayesian analysis to estimate the intrinsic and incompleteness-corrected size-luminosity distribution.                                                                                       |
| Purpose     | To measure and analyze the size-luminosity relation of galaxies within the redshift range of 6 to 9, using lensed galaxies and to investigate the systematic uncertainties in the choice of lens models. |
