ms2rms

Calculate standard deviation given a time interval of each trace.

How to Compile

1. Clone this repo by THIS COMMAND: git clone https://github.com/Cuda-Chen/ms2rms.git
2. Type make to compile.

Dependencies

• libmseed

Usage

$ ./ms2rms [mseedfile] [time window size] [window overlap] [a|r|j]

Where:

• time window size: measured in seconds. It should always bigger than 0.
• window overlap: measured in percentage. It should always smaller than 100.
• a|r|j: indicate output file format.
  • r: rms only
  • j: json only
  • a: rms and json

Output Format

.rms

<time stamp of the first window>,<station>,<network>,<channel>,<location>,<CR><LF>
<time difference between this window to the first window>,<mean>,<SD>,<min>,<max>,<minDemean>,<maxDemean>,<CR><LF>
<time difference between this window to the first window>,<mean>,<SD>,<min>,<max>,<minDemean>,<maxDemean>,<CR><LF>
...

Note

• This program can ONLY accept single channel record. Multiple channels result in incorrect output.
• The rms and mean value are rounded to hundrendth place.
