XBox Controller Angle of Fire Incorrect

I am using an XBox controller, right analog stick to fire a projectile in a 2D game, and using the right analog stick to create the angle that it fires. The analog stick reports the angles correctly, but it seems I'm interpreting the angle to always be off (by about 70 degrees counterclockwise, it seems).

I checked other suggestions on how to find the correct angle, but I can't figure out how I'm using that angle incorrectly. If you have any other advice for this code to make it better, feel free to commend other suggestions. Everything helps!

  var xAim = Input.GetAxis("R_XAxis_1");
  var yAim = Input.GetAxis("R_YAxis_1");
 
  
  // Calculate the angle of the thumbstick
  var targetAngle : float = Mathf.Atan2(xAim, yAim) * Mathf.Rad2Deg;
  
  //Debug.Log(targetAngle);
  var targetVector = Vector3(0, 0, targetAngle);
  
  if( Input.GetAxis("Triggers_1") > .5 && (allowFire)){
        Fire(targetVector);
  }
 }
 
 function Fire(targetVector){
     allowFire = false;
      var shot = projectile.Instantiate( projectile, transform.position, Quaternion.identity );
     //make sure player can't hit himself with it
     Physics2D.IgnoreCollision( shot.collider2D, collider2D );
     //turn to face where it's heading
     shot.transform.Rotate( targetVector );
     //Destroy automatically after time
     Destroy(shot.gameObject, 2);
     yield WaitForSeconds(.3);
     allowFire = true;
 }
