== Wave Mode Sampling == These parameters relate to data sets derived from helioseismic analysis of solar image data, specifically to global-mode analysis. No such data sets are currently available from any of the providers, so these search parameters have not yet been implemented. ==== Degree_Minimum ==== type: ''number''[[BR]] FITS keyword: ''L_MIN''[[BR]] ==== Degree_Maximum ==== type: ''number''[[BR]] FITS keyword: ''L_MAX'' The nominal minimum (maximum) of the spherical harmonic degree range associated with the data. ==== Degree_Step ==== type: ''number''[[BR]] unit: ''Ångström (10nm) / pixel''[[BR]] FITS keyword: ''L_STP''[[BR]] The spacing between spherical harmonic degrees in the data
