### Cosmomc: ACBAR and CBI

Posted:

**June 18 2006**Hi Antony,

I am trying to use the full data of ACBAR and CBI, i.e. including the data points that are not considered by default. But I have some questions.

ACBAR: I did not find the values in the last column of ACBAR_lge800_.dataset, beam uncertainty, in the ACBAR's paper or in its website. How can I obtain these values for data points that are not listed in ACBAR_lge800_.dataset? Also, how would the value calib_uncertainty=0.2 change?

CBI: The bandpower covariance matrix provided by the CBI website is quite different from yours, CBI2.0_2to14_matrix.dat. Can I use their covariance matrix without changing the code, or how can I obtain the correct covariance martrix for the full CBI data? Again, would the value of calib_uncertainty=0.026 change?

Thanks a lot!
