$R$-band light curves of optical afterglows

For many years, D. A. Kann collected optical and NIR data of long and short GRB afterglows. He combined the multi-band data to build composite $R$-band light curves. To honour his legacy, this repository releases the composite light curves that he shared with me many years ago.

All measurements corrected for MW extinction. They should be in the AB system.

Please let me know if you notice any mistake.
