Most recent major modifications or corrections to programs in PROSPE
       This table only lists reasonably significant modifications - smaller incremental changes are made all the time. To establish whether you are using the current version of a program check the version date at the top of the program listing or as displayed on running the program.

SVIEW_L
 Elimination of the irritating disappearance in Windows 10 of part of the bottom information line in both programs (as well as in FFTS, V6_20, and VKIEL)
JUL2020 XIAM_mod Modification by Sven Herbers of the XIAM program of Holger Hartwig, allowing the use of two more internal rotation parameters.

Accessory programs VIFORM, VADCAT , LINVAD  now allow operation of both RAM36 and RAM36hf within the scheme of the AABS package.
JAN2020 AABS Option initiated with key 4 programmed in both SVIEW_L and ASCP_L  for autoscaling the Y-axis of the current spectrum viewport.  Very useful for working with segmented spectra or highlighted transition sequences of varying intensity.
JAN2020 FFTS This program can now read and process .DAT files from the FTMW++ program of Jens-Uwe Grabow. 
A collection of such processed files can be further inspected and synthesised into a single spectrum with program V6_20 for integrated use within the AABS package.
JUl2019 FIDFIT FID fitting in the time domain (updated version of program DECAYSBN of Juergen Haekel from the Kiel laboratory)

JUN2018 AABS
PMIFST
FFTS		 Linux operation of these programs was tested on Ubuntu/Wine with installation steps as described in the links (note that such tests were carried out earlier but were much less successful).
FEB2018 ERHAM Improved integration of ERHAM with the AABS package: new instructions, and new ERHAMZ_R3, LINERH, ERHRES programs.
APR2017 PIFORM Significant update for improved stability and better automatic subset statistics (especially if .PAR and .LIN files are accessible together with the .FIT file).
MAR2017 FFTS New program for FFT processing of supersonic expansion free induction decay data (chirped pulse and Balle Flygare type).
DEC2016
Looks like PROSPE had a quiet 15th anniversary, at least when counted from its official creation date.  There has been further steady development over the last few years as highlighted for some of these more popular programs:
  • AABS -  for a quick check on new features you can inspect the key-maps sview_l_keys and ascp_l_keys but complete documentation is only available in the AABS_HELP.CHM file. Some specific modifications are:
  • SVIEW_L - more spectral modification and display options and the 0 key operation for inserting predicted lines into the fitting data file.  More detailed listing in the 'modification history' section of this file
  • ASCP_L - many improvements to the automatic difference frequency plots in the Loomis-Wood screen, further details in the 'modification history' section of this file.
  • PMIFST - direct input from CFOUR/Firefly/Gaussian computing packages, hydrogen bond detection options, generation of connectivity input for use in STRFIT
  • STRFIT - improved input error diagnostics, better documentation, new capabilities for high symmetry, easy exclusions of constants from fit
  • CORSCL - improved automatic generation of predictions for popular single and double isotopic substitutions
  • PIFORM - comprehensive statistics for subsets of the overall data set.  Various other post-processing programs in the PICKETT section have also been updated, as well as the crib_sheet and the annotated official documentation.
OCT2016 DJ New program for applying the venerable pseudo-diatomic approximation to weakly bound dimers.  Easy to use and carries out traceable calculations with the various versions of the formulae.
DEC2012 RAM36 Vadim Ilyushin's program for fitting internal rotation with 3 and 6 fold barriers made available
OCT2012 EVAL
KRA
 CORSCL		 All three programs significantly updated. EVAL now evaluates the much requested uncertainties in dihedral angles and CORSCL features automated prediction for single isotopic substitutions.
JUN2012 SVIEW_L Reworked keyboard input in order to cure the sporadic problem of lost keystrokes. B/W colour scheme now also possible. All users are highly recommended to upgrade.
DEC2011 PMIFST Rewritten gle script output with selection from several preset drawing styles.
DEC2011 AABS Many incremental changes and several new features including:
- modified line blanking and baseline subtraction in SVIEW_L
- settable frequency axis flags (V key) and Loomis-Wood comb mode (O key) in ASCP_L
FEB2011 Data New subpage created for primary data associated with past investigations, which is also to serve as a collection of worked examples.
AUG2010 PMIFST
ASCP_L
 Many changes to the generated gle scripts for easier incorporation of the resulting diagrams in presentations.
AUG2010 citation
 The recommended scientific paper citation for the PROSPE site (in response to specific questions on this matter from some users).
JUL2010 AABS Many changes to both ASCP_L and SVIEW_L, and to their documentation.  You need to download both EXE files and the AABS.CHM file (dated 29thJuly or later) in order to upgrade.
JUL2010 Crib_sheet
 New section on 'traps for unwary SPFIT users'  added as a reaction to regular reappearance of some problems.

The two AABS graphical viewers of spectra (SVIEW_L) and of predictions (ASCP_L) are now recommended also for standalone operation. The development of ASCP and SVIEW has been stopped, but their subpages should still be consulted for useful additional documentation.
