How to conduct the "SLR Validation" processing?

[Hanbing59]

Hi GROOPS team,

I am wondering what the correct processing config for the "SLR Validation" is. By "SLR Validation", I mean, just calculate and output the OmC residuals, which are a-priori residuals with a-priori models, orbits and station positions.

I tried to follow the program SlrProcessing but disabling the SlrProcessingStep->Estimate, expected that the output residual files from SlrProcessingStep->WriteResiduals would be what I want. However, it turns out the output residual files contain all zeros (except for the azimuth & elevation columns)

Instead of trying figure out by investigating the code, I think just post a question here may give me a more direct clue on it.

Thanks for any information I may have missed.

Best regards,
hanbing

For those who are also interested in doing "SLR Validation" with GROOPS, I would like to share my workarounds:

In the implementation of the processing step: writeResiduals, i.e. the process function of the class SlrProcessingStepWriteResiduals, I write out the reduced observations (data member SlrObservationEquation::l) on the column 4 (data3) to the output residual file.

In this case, if you want to do the SLR Validation only, just make sure you select the writeResiduals processing steps.
