ACM modes?

[Alaskan]

Did the F4E have ACM modes controlled by the pilot for the radar?

Yes, later blocks had ACM mode (CAA). Source USAF Phantoms by Anthony M Thornborough.

"USAF Phantoms by Anthony M Thornborough".

Do you recommend this book? Is it a good source of information?

Yes, A good solid read with lots of interesting information. Also Clashes, air Combat over North Vietnam 1965-72 by Marshall L Michel III

Yes there is boresight and Computer automatic acquisition (similar to vertical scan): radar sweeps in the vertical between -21 degrees to +57 degrees, but can only lockon between 45 degrees and -9 degrees in pitch due to computer limitations. The width of the scan depends on the version but it's either 7.5 degrees or 5 degrees including beam width, numbers are off the top of my head so take it with a grain of salt. The range is dynamically reduced as the antenna dips below the horizon to reduce main lobe clutter returns. 

Later versions of CAA also let you offset the scan pattern by 15 degrees left, right or centre.
