It's a bit of a mess these days as the required service volumes have been changed from what they used to be - and not in the same way across the board. In the US, they have introduced smaller service volumes in order to cater for the number of installations which can be present in a given area. In other places, the clearance sector has been reduced or even removed alltogether (I think this became reality but am not 100% certain) as the precision of the means to becoming established on the LLZ has increased.
That's probably the answer to why it is no longer in Jeppesen.
I do not have the picture in a digital format, but it used to be 25 nm within 10 degrees off the course line and 17 nm within 35 degrees.
I think the new US specification is for 10 nm in the clearance sector. Can't recall the range requirement for the +/- 10 degrees sector.
Should give you more to google on if it doesn't help in any other way.
