-Within is a list of simulation done since the beginning of the project. It has been partitioned such that simulations done with the original version of radiometer are in the bottom section, while simulations done with more up-to-date versions of radiometer are nearer to the top. Structure is as follows:

   * Date: Author, Title: pdf
     * Short description of contents within

-  * 2016, July 13: Levi Walls, Preliminary Love Wave Recoveries: {{:groups:homestake:meetings:preliminary_love_wave_recoveries.pdf|pdf}}
+Radiometer2:
+  * 7/16/16: Levi Walls, Preliminary Love Wave Recoveries: {{:groups:homestake:meetings:preliminary_love_wave_recoveries.pdf|pdf}}
     * Example showing the radiometer code for simulated Love wave recoveries works as it should
-  * 2016, June 30: Tanner Prestegard, Rayleigh wave eigenfunctions: {{:groups:homestake:meetings:2016_06_30_rayleigh.pdf|pdf}}
+  * 9/21/15: Levi Walls, Comparison of Rayleigh Wave Recoveries at Differing Observation Lengths: {{:groups:homestake:simulations:comparison_of_rayleigh_wave_recoveries_of_differing_observation.pdf|pdf}}
-    * Parameter estimation efforts for the Rayleigh wave eigenfunctions
+    * Looking at real data and using "realistic" parameters; still get junk results despite having long observation time.
-  * 2016, June 2: Ross Caton, Dispersion of Surface Waves in the Black Hills, SD: {{:groups:homestake:meetings:dispersion_v3.pdf|pdf}}
+  * 9/16/15: Levi Walls, Comparison of Rayleigh Wave Recoveries at Homestake: {{:groups:homestake:meetings:levi_radiometerrayleighhomestakedata.pdf|pdf}}
-    * Dispersion maps showing possible multipathing or other surface wave modes
+    * Looking at real data with perceivably realistic parameter values--did not yield any good skymaps
-  * 2016, May 5: Tanner Prestegard, Rayleigh wave amplitudes: {{:groups:homestake:meetings:2016_05_04_rayleigh_waves.pdf|pdf}}
+  * 9/14/15: Levi Walls, Rayleigh Recoveries with Realistic Parameters: {{:groups:homestake:simulations:rayleigh_recoveries_with_realistic_parameters.pdf|pdf}}
-    * Principal components analysis idea presentation
+    * Looking at real data using what was thought to be realistic parameters. “Junk” recoveries; i.e. no distinct signal was recovered—especially at low values of ϵ. Increasing ϵseems not to have a great effect on the signal recovery; however, the power diminishes slightly.
-  * 2016, April 7: Gary Pavlis, DUGL Weight Drop Source Data Analysis: Progress Report: {{:groups:homestake:meetings:april7weightdroptiming.pptx|pptx}}
+  * 9/4/15: Levi Walls, Effects of Varying α and є in Rayleigh Wave Recovery: {{:groups:homestake:simulations:comparison_of_rayleigh_wave_recoveries_of_differing_observation.pptx.pdf|pdf}}
-    * A technique to estimate the time delay between successive shots. Then use a shot that is nearest to one of our existing stations (which have absolute time) to get the absolute time for all the shots in that array.
+    * As α is varied, there is more variation in the recovered power signals than when є is varied. Frequently, there will be a strong signal recovered; then, a weaker signal (of the same shape) will be recovered 180° from the original.

+Radiometer:
+  * 3/1/2015: Noah Bittermann, Rayleigh Wave Diagnostics: {{:groups:homestake:meetings:rwavediagnostics4.pdf|pdf}}
+    * Looking at the effects of varying horizontal/vertical component of Rayleigh waves
+  * 8/21/14: Noah Bittermann, S-waves 2.0: {{:groups:homestake:meetings:swavetest_2.pdf|pdf}}
+    * Describes geometry of S-wave propagation; correctly recover injection position, shows strong dependence on scale of the array (or equivalently on the frequency of the wave), as well as on the array configuration. Changing polarization can change the shape of the recovered blob, but the blob is typically well centered.
+  * 8/21/14: Noah Bittermann, Frequency and Time Average Tests: {{:groups:homestake:meetings:swavetest_addl.pdf|pdf}}
+    *  found that averaging over recoveries at different frequencies improves the recovered position (have to check if this is dominated by the lowest frequencies), while averaging over longer periods of time yields the same checker board patterns.
