-This 2.1 version of the newest differential cross section calculator for exclusive single kaon electroproduction allows you to evaluate the differential cross section value for the large invariants' scales and any <a href="https://www.codecogs.com/eqnedit.php?latex=\cos{\theta}" target="_blank"><img src="https://latex.codecogs.com/gif.latex?\cos{\theta}" title="\cos{\theta}" /></a> values. Relatively fast and effective procedures make this program a convenient and reliable choice for data analysis in particle physics.
