Rachel beta tutorial videos

These videos were made with a pre-beta version, so some of the narration, buttons and menus have changed.  These will be updated with better narration for the release candidate.

''Note that some of narration in the later tutorials is outdated.  Prompts in the GUI terminal window should clarify these changes.''

===Installation and basic operations===

# To install Rachel and get it running for the first time, watch [http://www.pas.rochester.edu/~hayes/beta_rachel/rachel_installation.html Rachel Installation].
# A short video on [http://www.pas.rochester.edu/~hayes/beta_rachel/undo_redo.html the undo/redo buttons].
# How to [http://www.pas.rochester.edu/~hayes/beta_rachel/crash_recovery.html recover data from a crashed session].
# First steps: [http://www.pas.rochester.edu/~hayes/beta_rachel/reading_level_schemes.html Reading level schemes.]
# How to [http://www.pas.rochester.edu/~hayes/beta_rachel/add_matrix_non_collective.html add individual matrix elements].  This is most applicable to small, non-collective systems, such as the one in the sample file example2levels.txt file distributed with Rachel. 
# How to [http://www.pas.rochester.edu/~hayes/beta_rachel/add_matrix_collective.html add matrix elements systematically], i.e., for collective nuclei with rotational bands.
# How to [http://www.pas.rochester.edu/~hayes/beta_rachel/setting_up_calculations.html define experiments, Ge detectors and calculate predicted yields]. This video will show how to define experimental detector setup, data partitions and make instant plots as well.  Use the files fitting_example_levels.txt and fitting_example_matrix.txt included in the example files to quickly set up for this video. (The previous videos show how to load a level scheme and define or load a matrix.)  Note also that the current beta version 2.0.5 ''does'' allow arbitrary particle detector shapes to be defined.  The video narration has not been updated for all of the new detector options, and some prompts will be different from those in the video.
# A [http://www.pas.rochester.edu/~hayes/beta_rachel/basic_fit_example.html very basic example of fitting] including a correlated error calculation. The entire video is about 30 minutes long. You can follow along using the GUI on your system and the example files shown in the video, which are included with your Rachel distribution in the .../example_files/ subdirectory.
# More advanced selection of fit parameters are shown in this video on [http://www.pas.rochester.edu/~hayes/beta_rachel/experiment_planning_2.html experiment planning].

===Experiment planning tools===

# [http://www.pas.rochester.edu/~hayes/beta_rachel/experiment_planning.html Generating simulated data]. The errors in the simulated data are based on Poisson statistics and the expected number of days, beam current, etc. to estimate your ability to observe desired gamma-ray yields and to fit matrix elements to the observed yields. The present beta version applies ''optionally'' a quasi-gaussian random scatter of the predicted yield data [http://www.pas.rochester.edu/~hayes/beta_rachel/experiment_planning_2.html as demonstrated in this video] to better aid in predicting expected precision of fitted matrix elements. Watch this supplemental video to see how this works. You should also watch the [http://www.pas.rochester.edu/~hayes/beta_rachel/accuracy_testing.html accuracy testing video] to see if Gosia would be an appropriate analysis tool for your planned experiment.

===Testing the accuracy of calculations===

# [http://www.pas.rochester.edu/~hayes/beta_rachel/accuracy_testing.html Testing the accuracy] of your Gosia calculations and the applicability of Gosia to a planned experiment.
# Semiclassical Coulomb excitation codes have inherent adiabaticity and eccentricity limits. [http://www.pas.rochester.edu/~hayes/beta_rachel/adiabaticity_limit.html This video] shows how to test for these limits with an experiment that would ''not'' be appropriate for Gosia.
