Narrative:

Descending over beatty on the fuzzy 4 arrival into las from sea, I accidentally tracked outbound on the bty 130 degree radial instead of the bty 115 degree radial. We tracked outbound for approximately 10 DME, then corrected back toward the 115 degree radial. I was handling the radios and flying at the same time, while the captain was getting the ATIS. I believe this is why the error happened.
