The magnetically sensitive coronal emission lines provide information about coronal magnetic field via Hanle and Zeeman effects. As the measured emission are integrated over line-of-sight, the vector tomography must be used for deriving 3D magnetic field configuration. The unique solution for any field configuration exists when observations are done from both ecliptic and out of ecliptic plane and supplied by photospheric magnetic field measurements. When observations are only from the ecliptic plane, the number of field configurations which are possible to reconstruct are reduced. We study here what types of coronal magnetic field configurations can be reconstructed based on Hanle and Zeeman effects provided by CoMP and SOLARC instruments. Effect of noise in the data and uncertainty in 3D reconstruction of the coronal density and temperature are also studied.
