Frida-1 contains a large number of read in routines for neutron scattering instruments, for the two light scattering instruments operated at the Institute E13 of the Physics Department of the Technical University of Munich, and the optical Kerr effect spectrometer at LENS.

Neutron scattering read-in routines

The read in routines for neutron scattering are mainly focussing on time-of-flight spectroscopy. Routines for time-of-flight spectroscopy and the neutron backscattering spectrometer HFBS of the NCNR at NIST have continuously been maintained.

• r04 or r4 is the read-in routine for time-of-flight data of the IN4 spectrometer at ILL

• r05 or r5 is the read-in routine for time-of-flight data of the IN5 spectrometer at ILL

• r06 or r6 is the read-in routine for time-of-flight data of the IN6 spectrometer at ILL

• r10 is the read-in routine for neutron backscattering data of the IN10 spectrometer at ILL

• r10e is the read-in routine for elastic scans at the neutron backscattering spectrometer IN10 at ILL

• r13 is the read-in routine for neutron backscattering data of the IN13 spectrometer at ILL

• r16 is the read-in routine for neutron backscattering data of the IN16 spectrometer at ILL

• rdcs is the read-in routine for neutron time-of-flight data acquired at the DCS spectrometer at the NCNR(NIST). The data has to be converted to ASCII format using the DAVE program. Details on which data fields have to be included for the conversion will become available shortly. The routine might be modified to directly read-in the NEXUS format.

• rfoc data read-in routine for the FOCUS time-of-flight spectrometer at SINQ (PSI). This routine is thanks to F. Juranyi able to directly read-in NEXUS raw data.

• rfoco is the old read-in routine used for data acquired at the FOCUS time-of-flight spectrometer at SINQ (PSI). This routine requires preconversion of the NEXUS raw data to ASCII using a program written by A. Meyer that is available on-site.

• rhfbs is the read-in routine for the neutron backscattering spectrometer HFBS at NCNR(NIST)

• rhfbso is the read-in routine for the neutron backscattering spectrometer HFBS at NCNR(NIST)
  This routine shall be used for data predating August 2003 that has been preprocessed with a converter program available on site.

• rtof is used to read data acquired at the TOFTOF spectrometer at FRM-II.

• rrs read-in routine for the IRIS spectrometer at ISIS
  This routine was recently implemented and is still partly on an experimental stage.

Light-scattering read-in routines

• rf read-in routine for data acquired at the Fabry-Perot-Interferometer at the Institute E13 of the Physics Department.

• rr read-in routine for data acquired at the Raman spectrometer at the Institute E13 of the Physics Department.

• ro read-in routine for data acquired at the Optical Kerr Spectrometer at LENS.

The following routines may need revision. Changes of file format highly possible

• rMI is used to read data from Mibemol acquired at the Orphee reactor in Saclay.
• rNE is used to read data from the NEAT time-of-flight spectrometer at HMI in Berlin.
• rfcs can be used to read data of the FCS spectrometer at NCNR(NIST) that is currently
  out of operation.
