Narrative:

This is some follow up information for the previously submitted report concerning an near midair collision after takeoff from tus. After talking to the tower supervisor and reviewing the 10-9 chart; I have come to find out that there is a separate tower frequency for the parallel runway at tus that is not printed on the 10-9. I feel that my situational awareness and understanding of the event would have been enhanced had I been aware of this information. Is this an omission from the tus 10-9 chart that needs to be rectified? Immediately after takeoff; I noticed a light aircraft ahead of us and took evasive maneuvers. I had not yet called for gear up. It was an immediate response but not violent to where the passenger were even aware of it. During the evasive maneuver; there was a TCAS TA; I believe that it read out 300 ft. We told tower that we would file an near midair collision report and advised dispatch after we reached cruise altitude. My best guess is that the light aircraft had taken off from the parallel runway and turned the wrong direction.
