Defining the DATA flag*Some of the links on this page are to wiki pages that require ligo.org credentials. If you need to gain access to the information there, please contact us at email@example.com.
S5 Data setWe have made an effort to make available all S5 data that may be interpreted as a measure of gravitational wave strain. In most cases, the DATA flag was defined to be equivalent to times that pass CAT 1 vetoes from the CBC high mass search. This can be achieved with calls to the LIGO segment database with calls of the form:
/usr/bin/ligolw_segment_query -q -s 815155213 -e 875232014 -a H1:Science,H1:Injection -b H1:MISSING_RDS_C03_L2,H1:OUT_OF_LOCK,H1:AS_TRIGGER,H1:MISSING_RAW,H1:INVALID_DARMERR,H1:CORRUPTED_RDS_C03_LX,H1:PEM_INJECTION -t https://metaserver.phy.syr.edu /usr/bin/ligolw_segment_query -q -s 815155213 -e 875232014 -a H2:Science,H1:Injection -b H2:MISSING_RDS_C03_L2,H2:OUT_OF_LOCK,H2:AS_TRIGGER,H2:MISSING_RAW,H2:INVALID_DARMERR,H2:CORRUPTED_RDS_C03_LX,H2:PEM_INJECTION -t https://metaserver.phy.syr.edu /usr/bin/ligolw_segment_query -q -s 815155213 -e 875232014 -a L1:Science,L1:Injection -b L1:MISSING_RDS_C03_L2,L1:OUT_OF_LOCK,L1:AS_TRIGGER,L1:MISSING_RAW,L1:INVALID_DARMERR,L1:CORRUPTED_RDS_C03_LX,L1:PEM_INJECTION -t https://metaserver.phy.syr.edu
In addition, diagnostic plots of the data set revealed 94 additional seconds of data which were of very poor quality, and so were removed from the data set. These bad times were identified with the criteria that including them caused the standard deviation of all h(t) strain data in the GWOSC file to exceed 10-15. These 94 seconds are listed in this text file.
