I present an initial application of the Coronal Reconstruction Onto B-Aligned Regions (CROBAR) method to PUNCH polarimetric data. CROBAR was initially developed to capitalize on the field-aligned structure of the lower EUV corona, do it is likewise suited to reconstruct the largely radial structure seen in much of the PUNCH field of view. I will show reconstruction of synthetic PUNCH data provided by the mission team and compare the results to the simulation cubes used to make the synthetic data.I present an initial application of the Coronal Reconstruction Onto B-Aligned Regions (CROBAR) method to PUNCH polarimetric data.
