| For all other observers a common account called “obs2” can be used (ask the operator for the actual password). The toolbox performs some basic baselevel subtraction and filtering of strong radio-frequency interference (RFI) signals. Some parameters can be modified by hand if needed (see [[information_for_astronomers:user_guide:reduc_pointing|Reduction of pointing measurements]] for toolbox options). Transformation into NOD2 format, restoration of multi-horn data, transformation into right ascension/declination coordinates and Gaussian fitting for calibrators is done by dedicated automatic pipelines developed for each receiver. | For all other observers a common account called “obs2” can be used (ask the operator for the actual password).
