| 1. | Single Dish Flux Density Monitoring Centerline of Geodetic VLBI Sources. Since many compact sources have varying flux, if is important to monitor their correlated flux density in order to schedule geodetic VLBI sessions successfully. For the majority of the sources there is a strong correlation between variation of the total flux and variations of correlated flux, therefore single dish flux density measurements can be used to predict correlated flux changes. The Crimean Astrophysical Observatory put forward an idea of monitoring of the total flux of the sources observed in geodetic programs. We are planning to measure the total flux of the 114 frequently observed sources on the quarterly basis. The first campaign was successfully observed in December 2003. The measurement technique is discussed and first results are presented. |
