tau in WMAP5 vs. ACBAR papers
In the WMAP5 paper 0803.0547 the quoted value for tau in the LCDM model using the WMAP5 data is 0.087\pm0.017 (table 1). In the ACBAR paper 0801.1491 the quoted value for WMAP5 data alone is 0.086\pm0.008 (table 4), i.e. the same mean value, but half the error bars. The other cosmological parameters in the tables agree. Does anyone know the reason for this? (My first uneducated guess would be a typo in the ACBAR paper table 4.)

I asked the ACBAR team, and there is indeed a typo in the script which generated the values for table 4.
