Error analyses are made of ACR (Astrometric Calibration Regions along the celestial equator) and CMC13 (Carlsberg Meridian Catalogue 13), two astrometric catalogues compiled on the basis of CCD drift scanning observations and published respectively before and after 2000. Through a comparison with the UCAC2 (the second U.S. Naval Observatory CCD Astrograph Catalogue), the form and size of the errors are analyzed numerically. The main and possible sources of the errors are analyzed from the standpoint of observing mode and data reduction. It is found that there is evident magnitude difference between the ACR and CMC13 in the equatorial direction, and that there exists periodic variation close to the CCD field of view along the right ascension and also a systematic variation close to the size of reduction zone along the declination.
