Can anyone help me learn exactly what this card means and how it was used? I'm fairly new to this level of interest and I'm having trouble finding this type of specific information.

I'm also interested to know who would have entered the hand-written values, and when?

I can link to a higher-res scan if that would help.

They were velcro'ed next to pertinent instruments and switches for easy hands off "cue-ing" without having to thumb through a booklet. We've sold them for Cernan, Gordon, and McDivitt.

000:11:17 Scott: Houston, we've got 103 by 89.5.

000:11:22 Roosa: Roger, Apollo 9. Copy. [Pause.]

Public Affairs Officer - "That was Dave Scott giving the onboard orbital parameters, 103 [nautical miles, 191 km] by 89.5 [nautical miles, 166 km]. We will refine those later through tracking. FIDO says go."

[There is a greater than expected difference between the onboard orbital determination and the figures derived from the real-time ground tracking due to an incorrectly compensated bias of the X-axis accelerometer on the spacecraft. The bias error will be briefly mentioned to the crew before the SPS-1 burn at 005:03:00, discussed further at 007:18:48 and the bias compensation will be updated around 020:49:25.]

000:11:39 Roosa: And, Apollo 9, you are go in the orbit.

000:11:43 McDivitt: Roger.

000:11:47 Roosa: And your CMC is go; it is valid.

000:11:51 McDivitt: Okay.

000:11:56 Roosa: And, Apollo 9, the S-IVB has been safed.

000:11:59 McDivitt: Roger, safed. Do you have our apogee and perigee?
