...…high magnitude smooth signals or foregrounds. maxsmooth DCFs can be fitted with routines such as Basin-hopping (Wales & Doye, 1997) and NelderMead (Nelder & Mead, 1965) and this has been the practice for 21-cm cosmology (Sathyanarayana Rao, Subrahmanyan, Udaya Shankar, & Chluba, 2017; Singh &…...

...When jointly fitting an MSF and signal model we find that we can accurately recover the signal itself (see Bevins et al. (2020)). maxsmooth is applicable to any experiment in which the signal of interest has to be separated from comparatively high magnitude smooth signals or foregrounds. maxsmooth DCFs can be fitted with routines such as Basin-hopping (Wales & Doye, 1997) and NelderMead (Nelder & Mead, 1965) and this has been the practice for 21-cm cosmology (Sathyanarayana Rao, Subrahmanyan, Udaya Shankar, & Chluba, 2017; Singh & Subrahmanyan, 2019)....

...We find that the use of quadratic programming makes maxsmooth approximately two orders of magnitude quicker than a Basin-hopping/Nelder-Mead approach. maxsmooth rephrases the above condition such that ±m dmy dxm ≤ 0, where the ± applies to a given m....
