Explanation:

Polar-Areas Stellar-Imaging in Polarisation High-Accuracy Experiment (PASIPHAE) is an international collaborative sky surveying project.

• The survey will use two high-tech optical polarimeters to observe the northern and southern skies, simultaneously.
• It will focus on capturing starlight polarisation of very faint stars that are so far away that polarisation signals from there have not been systematically studied.
• The distances to these stars will be obtained from measurements of the GAIA satellite.
• By combining these data, astronomers will perform a maiden magnetic field tomography mapping of the interstellar medium of very large areas of the sky using a novel polarimeter instrument known as WALOP (Wide Area Linear Optical Polarimeter).

Hence both statements are correct.
