[MSNoise] One more clarification

Hi all, I was just reading through Taka'aki and Forents new paper using MSNoise, and was hoping just for a wee bit more clarification on the MSnoise processing scheme (wasnt quite clear in the docs). The paper says; "We first removed the instrument response from 1-day-long waveform to obtain ground motion in displacement. Daily displacement data were bandpassed between 0.08 and 2.0 Hz, down-sampled into 10 Hz, and split into 30-min-long data. Those 30-min-long data were spectral whitened in a frequency range of 0.1–0.9 Hz and then one-bit normalized. With those one-bit normalized data, the NCFs were computed for all possible combinations of components. Daily NCFs were then obtained by stacking 30-min NCFs." Q1) So just in terms of implementation in msnoise admin, the 30-min-long duration would be controlled by "analysis_duration" correct? Q2) If you remove the instrument response, is it always removed from a 1 day chunk, or is it removed from a chunk equal in size to "analysis_duration"? (the docs say 1 day, but I wasnt sure if this was just referencing the default "analysis_duration" time). Q3) This probably isnt the intended usage, but if you used "analysis_duration" longer than a day, would you expect things to behave? Thanks as always! -ashton p.s. paper; http://earth-planets-space.springeropen.com/articles/10.1186/s40623-016-053… -- Ashton F.
