Narrative:
Having been cleared to FL230 and the porte 9 departure SID from sfo, we departed on runway 1L. After contacting departure control we were instructed to stop climb at 4000 ft and turn left to 260 degrees. About then I noticed traffic to our right and slightly above, moving from right to left and assumed that we were advised to level at 4000 ft because of that traffic. When ATC advised us of traffic, I responded 'in sight.' by then the traffic, a B737 was crossing our nose at approximately 1/2 mi and 500 ft above. Upon landing at psp we were asked to call bay departure.
