Scale factor band for AAC-LD

hi..
  I am now modifying AAC-LC encoder to AAC-LD encoder. In AAC-LC for long blocks, the maximum SFB selected, MAX_SFB_LONG is 51 and for short blocks, MAX_SFB_SHORT is 15. In AAC-LD only long blocks is used. But since the frame size changes from 1024 to 512/480, I want to know what will be the SFB for AAC-LD for 512 and 480 frame size.

Thanks in advance

There should be sampling-rate dependent tables for 512/480 frame length in ISO/IEC 14496-3:2009 (or the older 2005 version).
