 * %Description
 * The HU52 undulator, a DCM, a fluorescence sample, and monitors.
+* This model does not contain any focusing mirror.
+* The sample is a kind of biological cell.

 * %Parameters
-* E0: [keV] Nominal energy at the Wiggler.
-* dE: [keV] Energy half-bandwidth at the Wiggler
-* sample_material: [str] Absorption data file for the sample
+* E0: [keV] Nominal energy at the source, in 0.6-8 keV.
+* dE: [keV] Energy half-bandwidth at the source.
+* sample_material: [str] Absorption data file for the sample.
 * sample_geometry: [str] OFF/PLY file name for sample 3D geometry, or NULL for a box.
-* dcm_theta: [deg] Rotation angle of the DCM. 0=set from energy E0
+* dcm_theta: [deg] Rotation angle of the DCM. 0=set from energy E0.
