Tamara-A

Tamara-A is an avatar of the deceased Tamara Adams created by Daniel Graystone, using the program devised by Zoe Graystone for her own avatar.

As Joseph Adama's payment for obtaining the meta-cognitive processor from Vergis Corporation, Daniel generates the avatar from records in various database in a holoband virtual world.

Upon Joseph's meeting of Tamara-A, she expresses to him that she cannot feel her heart beat, which only further deepens Joseph's loss. His outrage over this abomination causes a rift between Daniel and Joseph (Caprica pilot).

Joseph starts having hallucinations about the avatar and is shocked to learn from Daniel that she did not disappear when he removed his holoband, but is instead presumably still lost and confused inside the computer (Rebirth).

With the help of physical pressure from his brother Sam, Joseph convinces Daniel to let him see Tamara-A again. However, Zoe-A and Lacy Rand discover her within the Graystone mainframe and help her out into the larger virtual network, unwittingly preventing Joseph from meeting her (The Reins of a Waterfall).
