### Challenge 3

 Measured Data 18000467 49319591 85727464 89453452 74324712a 74324712b

### Notes:

18000467: Sparse Modeling (L1+TV regularization) - The raw reconstructed image from uvfits files solved with L1+TV regularization and L-BFGS-B algorithm from the bi-spectrum. (BSSpM)
49319591: Closure Only Imaging
85727464: Amplitude + Closure Phase Imaging
89453452: Bispectrum Imaging
74324712: CHIRP Method - For challenge 3 I have submitted 2 files that I obtain using 2 parameter settings. I believe both are incorrect, but I think param1 (74324712a) fits the visibility amplitudes slightly better.
