* Generate a solution with ''Q''. If the weighted RMS is < 150 ps, things are likely ok. You should be able to produxe a version 4 database and NGS file at this stage if you want to work on the data in VieVS/OCCAM/etc. This avoids calc/solve flagging ''outliers'' automatically. To proceed on to obtain a final solution, read on. | * Generate a solution with ''Q''. If the weighted RMS is < 150 ps, things are likely ok.

* Press ''P'' to proceed with detection & elimination & press ''S'' to save the results & generate a new solution. If the wrms is between 15 and 100 psec with the ''used observations'' precetage > 80%, then it's regarded as good. Significantly worse wrms/low acceptance suggests mishanded clock breaks, un- or mis-applied calibration, or maybe a bad station. | * Press ''P'' to proceed with detection & elimination & press ''S'' to save the results & generate a new solution.

* Assuming that you have a good solution, or one with known and uncorrectable problems, you can then go on to generate a final solution. | * Assuming that you have a good solution, or one with known and uncorrectable problems, you can then go on to generate a final solution. |
