I have the following list:
{{-1628.11740799393 - 557.339672450634 I}, {-1628.11740799393 + 557.339672450634 I},
{-920.324284271774 - 1508.13304084624 I}, {-920.324284271774 + 1508.13304084624 I},
{2107.28351459532}, {2145.53211042304}, {2207.19944421678}, {2289.69932193979},
{2318.0488541237 - 13.4030555095579 I}, {2318.0488541237 + 13.4030555095579 I}}
I would like to remove the complex numbers (Real & Imaginary parts) from this set and keep the real sets only which are 4 subsets in this case. I really appreciate any help in this regard.
