FFT Program / Pulsations
I know I haven’t updated in a while. I just haven’t been in much of a mood to write (or had the time). Classes started, so I’ve been extra busy. I won’t even try to recap since I can’t remember everything I’ve done in the past two weeks.
Running Sandy’s new nifty FFT program, I have found… nothing. I’m still looking for significant signals in windowed timing data. I looked at two GRBs and an SGR so far and found nothing that I can point to as a definite and measurable signal. One of the data sets of SGR 1900+14 did give me a very messy and broad blob of events above the threshold level (default is 99% confidence that it’s not statistical, I think) of the power spectrum, but I couldn’t look at that plot for long. I’ll have to go back to it.
Last thing I was able to do today was download some Crab wt data at random to attempt to find the pulsation period. I’m only using Spiders temporarily while my new computer, Everin, is being updated, but I might need to do some rearranging on Spiders before I can work tomorrow because it’s running out of space on /home.
Once all the bugs in the program and method are ironed out, and once I get my computer back, I’ll be able to run through all the good quality Swift GRBs with wt data quickly. I’ve been trying to get to that point since the start of the summer, but now I know we’re almost there.
