Those three steps listed by Khenra are IT. I just came here to post after figuring the same pattern out for myself.

As usual for some of these trickier Codex entries, you need to be non-host (maybe) in the Sortie version of the boss fight, and have Helios along. (Stealth is not necessary, despite some posts elsewhere claiming this.)

Additionally, it seems you can get more than one scan per mission. (I got 3 or 4 in one particularly buggy mission that ended in failure due to the raptors not appearing.)

And you do not need to drop the bomb, but it's pretty reliable to drop it in and just wait while it explodes under you.

Something that ALSO worked for me is letting them kill me while I stand on one of the Gravity Conveyors and use up a life. It made me fall for a second and sometimes Helios did his scan while I was being reborn.

Basically, just stand on the Conveyors one way or another (maybe snipe the raptor from there) and hope Helios does a scan. :D Grofit!
