Attention! W3,W4,H4,H5 are new data series. They are not on GGP database. Our gravimeter CD029 and CD030 have been rebuild at GWR: New small dewar, new cooling system. After that, they have interchanged the locations. CD029 is now at Bad Homburg (H4, H5) CD030 is now at Wettzell (W3, W4) Regards, Peter Wolf
