      fix plot styles · a3950e4d
      Kevin Kuns authored
      * fix bug where default styles don't check if a property has been defined with an alias (e.g. lw instead of linewidth)
      * make minor grid more transparent

      quantum noise uses test mass susceptibility for SQL strain · aa8a15ec
      Kevin Kuns authored
      * The quantum noise calculation uses the test mas susceptibility instead of the free mass approximation in shotradSignalRecycled.
      * The free mass approximation is still used in shotradSignalRecycledBnC and the functions in squeeze.py

      Suspension thermal noise sub-budgets · 10f24a98
      Kevin Kuns authored and Jameson Rollins's avatar Jameson Rollins committed
      Adds suspension thermal noise sub-budgets. This addresses 1/3 of #51. Suspension thermal noise can now be broken up into horizontal and vertical noise of each of the suspension stages. With one exception, which does not change the total noise, the calculation is the same as the current calculation but the contributions of each stage and direction are tracked separately.
      
      In the current calculation the horizontal and vertical spring constants of each stage are broken up into an upper and lower joint and are stored separately. The total suspension thermal noise is then calculated by adding the contributions of each of these joints using the appropriate temperature of each joint. Instead of adding the contributions of each joint all at once, this MR makes it possible to track each stage with separate `Noise` classes and add them all to a sub-budget.
      
      The noise for each stage is the sum of the noise from that stage's lower joint and the noise from the upper joint of the stage below. In the case of the top mass, the contribution from the upper joint is also included. In the current calculation, for the upper stages, the imaginary part of the horizontal spring constant is equally distributed between the upper and lower joints while it is only attributed to the upper joint for the test mass. The one change this MR makes to the calculation itself is to distribute this equally between the top and bottom joints as is done for the upper stages.
      
      The imaginary part of the vertical spring constant is only attributed to the upper joint of each stage. The blade springs are the only contribution to the vertical spring constant for the upper stages while the lower stage also includes the continuum fibers or ribbons. It's unclear how to break this up into an upper and lower stage as is done in figure 14 of https://arxiv.org/abs/2001.11173, so this MR does not have vertical noise of the test mass. (The noise is included, it's just attributed entirely to the PUM.)
