Is there a neat way to "not" run the internal Boltzmann solver (for perturbations) in CLASS code and rather just solve for the background quantities? This way I can save the time otherwise spent in evaluating the perturbations and transfer functions. I am only interested in the time evolution of background quantities.

1. How does the CLASS Code save time for background quantity evolution?

The CLASS Code allows for a more efficient and streamlined process of evolving background quantities by automating certain tasks and reducing the need for manual adjustments.

2. Is the CLASS Code easy to implement and use?

Yes, the CLASS Code is designed to be user-friendly and can be easily implemented into existing systems. It comes with detailed instructions and support to help users get started quickly.

3. Can the CLASS Code be customized to fit specific needs?

Yes, the CLASS Code is highly customizable and can be adapted to suit the specific requirements of different projects or applications. Users can adjust parameters and settings to tailor the tool to their needs.

4. What are the benefits of using the CLASS Code for background quantity evolution?

Some of the key benefits of using the CLASS Code include increased efficiency, reduced manual labor, improved accuracy, and the ability to easily track and monitor changes in background quantities over time.

5. Are there any limitations or drawbacks to using the CLASS Code?

While the CLASS Code offers many advantages, some limitations may include the need for basic programming knowledge to make customizations and potential compatibility issues with certain systems or software platforms.
