The Channel Information System (CIS) is a searchable online database of all the aLIGO channels in the frames. 

 

From the main page, cis.ligo.org, you can browse channels by the Tree, or search for particular channels in the upper right. 

 

 

The ultimate goal is to input detailed descriptions for all channels in the science frames (this is an ongoing project with a deadline goal of the start of O1, so you may still find unfilled science channels). 

 

Here's a SEI channel example (motion of the HAM2 optic table in Y): https://cis.ligo.org/channel/48527

 

The CIS also stores core channel information, including sampling rate and units, pulled directly from the DAQ configuration files (channel units are incorrect since the DAQ doesn’t know about units - a feature request has been submitted for the RCG).

 

 

Here also is a reminder pointer to the Hanford summary pages: https://ldas-jobs.ligo-wa.caltech.edu/~detchar/summary/

 

Check out the FAQ or ping any detector characterizer (some contacts listed in the FAQ doc) if you have any questions.
