After yesterday's Nobel celebration we are back on track . I believe I promised something on #data #analysis
A thread šŸ§µon how we extract the data from our #robot beamtime @desynews @p021_desy and how we figure out the #arrangement of #atoms in our samples /@RPittkowski 1/6
We get these beautiful 2D images from where the #scattered #X-ray beam hits the detector plate. What you see below is the scattering recorded for LaB6 - not surprising that we use it as a standard for calibration when you look at the beautiful #rings 2/6
By radial integration we get a 1D diffraction pattern, which shows distinct Bragg peaks for each ring on the 2D image. I made a very boring #GIF where you can see how the #rings relate to #peaks in the pattern 3/6

#Periodic Call Auction for Illiquid Scrips was brought in Feb-March 2013 put a lot of illiquid stocks in JAIL where trades happened once in an hour. It was reversed in December 2013. #BSESmallcapIndices made a new low in August 2013. nooreshtech.co.in/2013/04/periodā€¦
Deja Vu 2018 the target now is Liquid Scrips which have a lot of volumes and have gone up !! How many different ways regulators can find to trouble the system !! Some more stocks will keep getting added/deleted. Hopefully, like before the measures get reversed in next few months.
Another regulation is the #Smallcap, #Midcap, #LargeCap Classification wherein now the Regulator will decide the Universe for Mutual Funds and keep coming out with classification every 6 months which depends on price moves !!! Another pain to the system.
