Inconsistency between WMAP data and released map

Understand

A remarkable inconsistency between the calibrated differential time-ordered data (TOD) of the Wilkinson Microwave Anisotropy Probe (WMAP) mission, which is the input for map-making, and the cosmic microwave background (CMB) temperature maps published by the WMAP team is revealed, indicating that there must exist a serious problem in the map making routine of the WMAP team.

• This inconsistency is easy to be confirmed without the use of WMAP map-making software.
• In view of the importance of this issue for cosmology study, the authors invite readers to check it by themselves.
