First off I've been able to get some agreement between Asti Bhatt's electron line program and my own. I think she's doing a similar process but her dissertation, from which figure one is taken from, predates the 2011 Kudeki, Milla paper this repository is derived from. \r\n\r\nTo get the agreement I have changed the software. The sampling rate of tau, the lag parameter for the single particle ACF, is driven by the largest frequency component desired for the ISR spectrum. The numerical integration algorithm will basically keep integrating over tau until the difference is smaller then the desired setting. I have run into memory issues when I would use too many samples. I will need to make some sort of setting to keep this from happening in the future. \r\n\r\nThere are a couple of extra aspects that I will need to address. First off the ion line will have components that are larger in frequency than should be physically possible. I'm thinking of adding a piece of code to see the ion line to zero after a certain frequency. Otherwise I think I'm just going to put a note that the ion line acts unphysically after a certain frequency. This frequency is on the order of plasma frequency so it should impact anything I'm doing right now.\r\n\r\nOn other aspect is that the single particle ACF used to calculate the Gordeyev integral for the case with a magnetic field and no collisions is slightly different between Hagafor's publications and the Kudeki and Milla publication. I'm not sure how much of difference this makes and need to investigate it further. \r\n\r\nI'm going to keep this open for now and will hopefully close this issue soon.\r\n\r\n![screen shot 2016-04-23 at 11 59 39 am](https://cloud.githubusercontent.com/assets/2608303/14762544/e5834e12-094a-11e6-9f2c-83e1ae8f3283.png)\r\n\r\n\r\n![eliniline2wb](https://cloud.githubusercontent.com/assets/2608303/14762534/ba429d70-094a-11e6-857f-12197480d178.png)\r\n"}}
