Under the assumption that the concordance Lambda-cold dark matter (CDM) modelis the correct model, we test the cosmic microwave background (CMB) anisotropydata for systematic effects by examining the band pass temperature residualswith respect to this model. Residuals are analysed as a function of angularscale l, galactic latitude, frequency, calibration source, instrument type andseveral other variables that may be associated with potential systematiceffects. Our main result is that we find no significant systematic errorsassociated with these variables. However, we do find marginal evidence for atrend associated with galactic latitude indicative of galactic contamination.Comment: 33 pages, 11 figures, 4 tables, ApJ accepted, extends the analysis of astro-ph/0301490 to include the WMAP data, uses aastex.cl
