+*
+* Estia is a vertical sample, focusing reflectometer for small sample
+*
+* %Description
+* The instrument consists of a two part elliptical feeder that focuses onto 
+* a slit mask that defines the sample footprint, called virtual source.
+* The virtual source is imaged on the sample position with a Selene 
+* type neutron guide (two ellipses).
+* This version of the instrument, used in the ESS butterfly moderator, 
+* has two vertical Selene guide systems that share the same focal points.
+* The two guides are only implemented in the feeder as the selene mirrors
+* are part of the upgrade program.
+*
+* %Parameters
+* omegaa: [deg]  sample rotation omega
+* sample: flag to switch between     (0) sample Ni/Ti-multilayer
+*                                    (1) reference ( R(q_z) = 1 for all q_z )
+*                                    (2) Ni-film on silicon
+*                                    (3) Natural SiO2 on silicon
+*                                    (4) monitor instead of sample (normal to beam)
+* sample_length: [m] Size of sample in beam direction, also controls virtual source opening
+* sample_height: [m] Size of sample in vertical direction, also controls virtual source opening
+* 
+* operationmode: operation mode      (0) high-intensity specular reflectivity
+*                                    (1) almost conventional TOF
+* over_illumination: [m] Extra opening of virtual source compared to sample size
+* theta_resolution: Delta theta / theta  adjusted with the slit (operationmode=1)
+* 
+* lambda_start: [A] Beginning of simulated wavelength range
+* lambda_end:   [A] End of simulated wavelength range
+* enable_gravity: [0/1] Use gravity in elliptical guide model.
+* enable_chopper: [0/1/2/3] Activate chopper component if !=0. Numbers larger than
+*                           1 define the number of pulses per chopper opening.
