Oxygen content of EP Mars atmosphere?
Is there any info on the oxygen content of the partially terraformed Eclipse Phase Mars? I looked around but couldn't find it.

Nope
There is no direct info on oxygen. Ostensibly there are places on Mars where Rusters can breath unassisted. Page 305 of the Book says enhanced respiration allows a character to breath comfortably at pressures as low as 0.2 atmospheres. That number is all but useless unless you assume they're talking about Earth's atmospheric composition -- which is 20% oxygen. You might conclude that Mars has an atmosphere comprised of 20% oxygen at a pressure of .2atm and a temperature of -80C. (in my opinion that is [i][b][u]EXTREMELY[/u][/b][/i] unlikely after only 50 years of terraforming.)

The daytime temperature is
The daytime temperature is like 8 degrees Celsius - that is in the source material. Once you hit that tipping point of melting the southern polar dry ice .2 atm and 8 degrees seems believable to me in a very short timeframe. If they liberated some nitrogen (it mentions ammonia/ice asteroid bombardment) the atmosphere would be somewhat higher pressure than even .2 atm. Whether or not you could hit that tipping point in say 25 years and get the atmosphere to the 21% oxygen range in another 25 years is beyond my knowledge. I'll do a 500 gigawatt fusion reactor back of the envelope calculation and see how much damage/change I can do to the environment with it if it was dedicated to terraforming efforts. EDIT: I read about soil denitrification via nanites and tailored life forms too.
