I'm trying to construct a Fisher Forecast for the upcoming S4 CMB survey. I don't understand what the C_l is in this formula. It is H(z) and the Angular Distance? Or is it some covariance matrix and if it is a covariance matrix how do I calculate it considering the experiment hasn't been done...

I'm trying to recreate the results of this paper https://arxiv.org/pdf/1607.08016.pdf to obtain the constraints for the matter density and Hubble constant h. However every time I try to create there results my Fisher Matrix has elements of order of 10^14 which is far to high. I suspect this is...

Hello, I am writing a (mock) proposal for gaining some observation time on a telescope. One part that I am having a hard time with is, what considerations are made when deciding how large a field to survey? Are astronomers primarily constrained by the amount of time they are likely to be...

I know these days everyone is bombarded with companies asking for feedback, but this one is REALLY important. I can't look inside your heads to know what you think and I know many have little problems and don't want to start a whole thread on it. Now is your time. This community exists for its...

I'm building a(n online) survey and the client has specified many question types, such as slider, Lickert Scale, checkboxes, matrix, radio, free text, etc. (so, the list is a mix - of question types and visual representations of answer types) The very first one on the list simply called JAR...
