→ Plot CCF vs Time

This plot shows the cross-correlation functions (CCF) vs time. The parameters .. include:: /clickhelp/msnoise-cc-plot-ccftime.rst

allow to plot the daily or the mov-stacked CCF. Filters and components are selectable too. The --ampli argument allows to increase the vertical scale of the CCFs. The --seismic shows the up-going wiggles with a black-filled background (very heavy !). Passing --refilter allows to bandpass filter CCFs before plotting .

Example:

msnoise cc plot ccftime YA.UV06 YA.UV11 will plot all defaults:

../_images/ccftime.png

For zooming in the CCFs:

msnoise cc plot ccftime YA.UV05 YA.UV11 --xlim=-10,10 --ampli=15:

../_images/ccftime_zoom.png

It is sometimes useful to refilter the CCFs on the fly:

msnoise cc plot ccftime YA.UV05 YA.UV11 -r 0.5:1.0:

../_images/ccftime_refilter.png

→ Plot Interferograms

This plot shows the cross-correlation functions (CCF) vs time in a very similar .. include:: /clickhelp/msnoise-cc-plot-interferogram.rst

manner as on the ccftime plot above, but shows an image instead of wiggles. The parameters allow to plot the daily or the mov-stacked CCF. Filters and components are selectable too. Passing --refilter allows to bandpass filter CCFs before plotting .

Example:

msnoise cc plot interferogram YA.UV06 YA.UV11 -m5 will plot the ZZ component (default), filter 1 (default) and mov_stack 5:

../_images/interferogram.png

→ Plot CCF’s spectrum vs Time

This plot shows the cross-correlation functions’ spectrum vs time. The .. include:: /clickhelp/msnoise-cc-plot-spectime.rst

parameters allow to plot the daily or the mov-stacked CCF. Filters and components are selectable too. The --ampli argument allows to increase the vertical scale of the CCFs. Passing --refilter allows to bandpass filter CCFs before computing the FFT and plotting. Passing --startdate and --enddate parameters allows to specify which period of data should be plotted. By default the plot uses dates determined in database.

Example:

msnoise cc plot spectime YA.UV05 YA.UV11 will plot all defaults:

../_images/spectime.png

Zooming in the X-axis and playing with the amplitude:

msnoise cc plot spectime YA.UV05 YA.UV11 --xlim=0.08,1.1 --ampli=10:

../_images/spectime_zoom.png

And refiltering to enhance high frequency content:

msnoise cc plot spectime YA.UV05 YA.UV11 --xlim=0.5,1.1 --ampli=10 -r0.7:1.0:
