This tool provides a variety of local PSVCs (Paleosecular Variation Curves) as reference curves, each designed for specific areas. In addition, it includes several global and regional models (harmonic expansions of the geomagnetic potential) that can be used to generate synthetic PSVCs at the location of interest. Here is a list of the available curves included in the tool, along with their respective references (if you would like to have your curve included in the tool, please, contact paleomag@ucm.es):
