  • Extras... dialog box added (Edit menu). Permits user control of memory allocation, text and symbol sizes and scaling of plots printed or copied to the clipboard.
  • VGPs added to statistics.
  • Info box improved (bedding, core orientations, mass or volume added).
  • J/Jo plots work same as other graphics windows.
  • Core coordinates enabled.
  • "Delete selected" added to Least Squares window.
  • Many bugs in the statistics removed.
• Changes from v1.4:
  • Error in id's on strat plot removed.
  • Update to strat levels possible through "Remake .STEP...."
• Changes from v1.4.1:
  • Printing of plot headers fixed for non-100% scales.
  • Warning added if least squares directions not found in .SAM file for strat plot.
  • "Watson" stats accelerated somewhat.
• Changes from v1.4.2 (and later 1.4's):
  • "Edit Headers..." option added.
• Changes from v1.5
  • Fixed "Delete LSQ directions" option so that directions were correctly deleted from current session
• Changes from v. 1.5.1:
  • Fixed error in "Remake .STEP" (was overwriting site lat, lon info)
  • "Edit Header..." now updates the data list window.
• Changes from v. 1.5.2:
  • Fixed least squares strat plot (wouldn't read strat levels from .SAM file).
  • Added "Equal Area Options..." to Edit Menu.
  • Modified reference directions plotted on Equal Area plots.
  • Added magnetic declination and "Recalculate from Core" to "Edit Header...".
  • Added mean strike and dip to .SAM file.
  • Fixed minor memory error (wouldn't allow <50 demag steps/sample)
• Changes from v 1.6:
  • Fixed special case of 2 points with same demag level for J/Jo plot.
• Changes from v 1.6.1:
  • Fixed large bugs in "Edit Header..." command; core coordinates were incorrectly stored, data files potentially damaged.
• Changes from v 1.6.2:
  • Missing sample files no longer included in sample list, but warning given when site opened.
  • Orthographic (E-W) Zijder plot added.
  • Color added to plots.
  • Statistics now in menu bar.
  • Strat options in menu bar.
  • Cleaned up "positive down" strat option.
  • Added view by sample or ID to least-square fit dialogs.
  • Fixed (for ever, I hope) crash when canceling printing.
  • Save mean directions added.
  • Double-clickable documents added.
  • Component J/J0 plot added.
  • VGP latitude added to Strat Plot options.
  • Excessive refreshes of windows fixed (?)
  • Clicking on all points in all windows will produce an id in the upper left corner (Moment/MAD column in the old strat plots would not do this).
• Changes from v 2.0 betas
  • Equal area plots now correctly drawn with circles (hurrah!)
  • Symbol and text sizes and id options now saved between sessions.
  • Site Strat and EQplot "Cancel" button properly enabled.
  • Carriage return in "New Sample" dialog properly enabled.
  • Windows updated for empty sample files.
  • Refreshe of screen forced after printing.
• Changes from v 2.0:
  • Tinkered with "mouse-click" problems in list window and dialogs that have lists in panes; fixed two problems related to this.
• Changes from v 2.0.2:
  • Fixed failure to plot Fisher confidence cones in Site Equal Area plot.
  • Fixed failure to save Fisher mean from Least Square plot.
  • Addition of "sites" (View by sample/site), change to .sam format.
  • Modified "Select Points" option so it is active merely by holding down the option key.
  • Modified "Select Points" so that points in both Zijder and Equal Area plots are grayed out together if both views are displayed. (The list window remains unchanged).
  • Returned statistics from menu to dialog box (but separate from selection of points dialog).
  • Added reversal test.
• Changes from v 2.1 beta 2:
  • Fixed bug in New Site... command that caused a crash.
  • Fixed Import to allow creation of CIT header-only files (use 1-line header and include no data).
  • Fixed documentation on import format.
• Changes from v 2.1 beta 3:
  • Fixed bug that crashed program when strat levels were constant.
  • Corrected bug crashing changes to strat levels.
• Changes from v2.1 beta 4:
  • Fixed bug that crashed code when reselecting group equal-area or least-squares equal area plot.
• Changes from v2.1 beta 5:
  • Improved reporting of crashes due to memory problems (though these still have to be fixed by the user)
  • Fixed display of plane fits in least squares equal area plot.
  • Fixed error in saving Fisher mean to .means file.
  • Fixed minor text size problem.
  • Added McFadden and McElhinny Fisherian line and plane statistics routine.
  • Arc segments used in fitting planes or circles now saved in .lsq file. Old format files are updated upon opening (watch out if the original data files are now missing!).
• Changes from v2.2 betas 1&2:
  • Eliminated creation of phi ranges for line fits.
  • Fixed crashes due to inclusion of perfectly linear data.
• Correction from v2.3 beta 4:
  • Corrected occasional erroneous hemisphere on VGP longitude
• Correction from v2.3 beta 5:
  • POTENTIALLY NASTY BUG: crash when doing Fisher Line+Plane with only one plane/circle; could also produce erroneous means and errors. Latter might be visible in comparing geo vs. tilt- corrected results for homoclinal localities.
• Changes from v2.3 beta 7:
  • Addition of plotting options for plane/circle fits in lsq strat plot
• Changes from 2.3.1 beta 1
  • Fix of minor bug that would crash with "Consider upping limits in Extras.. dialog at line 3097" error (was miscounting number of sites in unusual situations).
• Changes from 2.3.1 beta 2
  • Fix of minor bug that would crash when changing sites after having done statistics on the locality or LSQ equal area plot.
