In Version 7.41 Ñ June 2016 - updated detector dead time constants for new electronics - 4 data sets can be ÒNSORTedÓ at once - event mode processing is more fully supported - macros are ready for the future release of Igor 7 and planned support for 64-bit versions - preparations for new data file format and VSANS instrument ÑÑÑÑÑÑÑÑÑÑ In version 7.20 -- June 2013 - Polarization procedures have been improved - Full support for the new 10m SANS instrument at NGB have been added, including SASCALC - Event mode data can now be processed through a convenient panel. Data collected in oscillatory, stream, TOF, or TISANE modes can be visualized, sliced, and processed. An XOP has been written to speed up the processing of these (often) very large files. See Event Mode Data - A panel to allow batch fitting of a single model to a large number of data sets has been implemented. It allows full control of the input guesses, data range, and held and constrained parameters. Once the starting information is gathered, the fits run unattended and save reports of the results. See: Auto Fit (or Batch Fitting) - Package loaders for processing data from various facilities have been consolidated onto the Macros menu rather than separate templates. Data handlers from different facilities cannot be loaded into the same experiment. ------------------------------------ In version 7.10 -- March 2012 SANS Reduction: - Polarization reduction procedures have been added - Full 2D error propagation has been added. It can be exported as 2D QxQy? ASCII and used for 2D analysis in the NCNR Analysis macros or SASView. - Gravity effects have been fully included in the 2D resolution function Analysis: - A beta version of real-space modeling has been added, allowing Debye's sphere method to be used to calculate the scattering from 3D structures in real-space. FFT version of the calculation provides 2D information, and a binned distance method provides a much faster calculation. ------------------------------------ In version 7.04 (26 NOV 2010) - A Rebinning panel allows re-binning of 1D data. - New menu organization of the 1D operations. - New Data Management panel enabling copying, converting, and batch conversion of file formats. - New options for curve fitting -- residuals and textInfoBox can be appended to the graph, and the standard deviation of the fitted parameters is now added to the table in the main Fit Panel. - 2D resolution smearing has been added. - For the Patch panel, one now can use wild card at the end of the distance, so for example 13* will find 13.17m, and 4* will find 3.9995m. Also loosened the criteria for matching the SDD in the MRED panel. - 2-Yukawa structure factor has been added. Support for P*S combinations is coming soon. - Arrow buttons on RAW data will search +- 10 files, in case some file numbers were skipped. - When desmearing USANS data, the high-Q slope does not need to be re-calculated. - XML output is now an option. - Numerous operational fixes for ANSTO, ILL, and HFIR data reduction. - USANS correction for detector dead time has been updated. ---------------- In Version 7.0 (April 2010) This release is a unified package where all of the reduction and analysis components can be loaded into the same experiment making analysis a convenient and integral part of reduction. What's New in SANS Analysis - A Simple Global Fitting module has been added that is simpler to set up global fitting for the special case of two data sets, typically one USANS set and one SANS set from the same sample. - Genetic Optimization has been added as an optional search method for non-linear fitting. (Andy Nelson, ANSTO) - Reduction and Analysis can now be carried out in the same Igor experiment. Reduction and analysis modules can be loaded as needed, and hidden when no longer in use. - Reduced 1D data in canSAS standard XML format can be loaded for analysis. - Complex constraints of coefficients can be entered as well as simple bounds. See Parameter Constraints - Experimental data that has been modified (trimmed, rescaled, etc.) can be easily saved to disk. What's New in SANS Reduction - Simulation of SANS data has been added. Working with the Analysis models, you can now optimize the instrument setup for the expected scattering of your sample while also obtaining estimates of countrates and counting statistics in a simulated data set. See SASCALC , Simulation of 1D SANS Data, and Simulation of 2D SANS Data. - Reduction and Analysis can now be carried out in the same Igor experiment. Reduction and analysis modules can be loaded as needed, and hidden when no longer in use. - Patching of raw data files is now easier with improved filtering to locate files. - Reduced 1D data is now written out in canSAS standard XML format. - General arithmetic operations can now be performed on two 1D data sets, improving the former Subtract_1D operation. What's New in USANS Reduction - Simulation of USANS data has been added. Similar to SASCALC for SANS, you can now adjust the angular ranges and steps, optimizing the instrument setup for the expected scattering of your sample. See UCALC and Simulation of USANS Data. - Reduced 1D data is now written out in canSAS standard XML format. - Individual raw (.bt5) files can be added together to improve statistics if a sample is re-measured at a single angular range. See Adding Raw BT5 Files. - Two full data sets (all angular ranges) can be added together to improve statistics. See Adding Two Data Sets. 11/2010 SRK
