The facts on the card
The card carries these facts from its Wikipedia article.
- The "Cold Spot" is approximately 70 μK colder than the average CMB temperature, whereas the root mean square of typical temperature variations is only 18 μK.
- At some points, the "cold spot" is 140 μK colder than the average CMB temperature.
- The radius of the "cold spot" subtends about 5°, it is centered at the galactic coordinate lII = 207.8°, bII = −56.3°.
Why it is Uncommon
Rarity in WikiCards follows a year of Wikipedia page views: the most read articles become Epic and Legendary cards. The CMB cold spot article was read about 43,000 times in a year. ATK comes from the length of the article and DEF from its quality, so this card hits with 66 and blocks with 57: each hit it takes is cut by 23 %.
