DAVE Screenshots

DAVE 2 main application window       The main application window of DAVE 2.
DAVE 2 documentation       The integrated documentation interface in DAVE 2.
surface plot       Creating multiple surface plots in a single window using the Window Layout feature to create multiple views.
2D line plot       A 2-dimensional line plot in DAVE 2. Note grid in the T-K plane.
Slice operation       The slice operation interface that enables the user to generate a 1D slice out of a 2D data along the x- or y-axis.
FANS Reduction       FANS Data Reduction main window.
3DenPro       Visualization of the Fourier density map (F observed) and corresponding atomic positions for a simple spinel structure measured by single crystal x-ray diffraction using the 3DenPro module.
TAS Scan Mapper       Visualization of the scattering plane of a TAS measurement highlighting the sources of spurious features in the measured scan using the TAS Scan Mapper module.
NSE Data Reduction       NSE Data Reduction main window.
mslice       Main window of the Mslice module. Mslice is used to reduce, visualize and analyze time-of-flight and other multi-detector instruments. It is particularly geared towards handling data from single crystal samples.
mslice volume       A volume visualization created using Mslice. Mslice can handle any arbitrary multi-dimensional data defined as intensity as a function of several independent variables.
mslice slice       Scattering within a plane extracted using Mslice.

DAVE main screenshot       The main DAVE application interface.
PAN screenshot       Using the data analysis module, PAN, to perform
least squares fit to simulated HFBS data.
XSECTION screenshot       Using the Neutron cross section Calculations tool to
determine the neutron cross section of a compound.
Neutron cross section table (scattering + absorbtion)
for all elements are also included.
Fourier Transform screenshot       The Fourier Transform Toolkit (CVS Build only).
The intermediate scattering function for tunneling
in methyl iodide. The data were taken using the NG2
backscattering spectrometer. Two inelastic peaks in S(Q,E)
manifest themselves as an oscillation in the time-domain.
The effects of instrumental resolution are evident.
databrowser screenshot       View of the main Data Browser interface showing
tree widget containers for data (1D and 2D) and plots (1D and 2D).
Also shown is an example of an image view of a 2D dataset
as well as a line plot of multiple 1D datasets.
databrowser screenshot       Surface view of a 2D dataset with the Data Browser.
Almost every attribute of the visualization can be customized.
The location of the excitations can be determine by fitting the data
using the PAN least-squares fitting module within DAVE.
DCS Mslice screenshot       Snapshot of session analyzing NDMAP single
crystal data using DCS Mslice.
ASCII screenshot       Reading ASCII data (from values extracted from a
fit in PAN fitting module) using the ASCII data reader.
RAINS screenshot       A quasielastic neutron scattering data set analyzed
using a diffusion within a sphere model in the RAINS
application module.
FANS screenshot       Performing data reduction with the FANS
data reduction module.
MARS planner screenshot       Planning for an experiment on MARS by checking the effects
of various instrument configuration parameters using the
MARS Tools Experiment Planner.
MARS reduction screenshot       Performing data reduction with Reduce MARS Data module.
MARS calib screenshot       Using the MARS analyser Banks Calibration module to
calibrate detectors on the MARS instrument.
