• Reduced frames directories and names:

The reduced frames are located on the LDAS disks at Livingston and at Hanford.  LLO reduced frames contain 75 channels, LHO reduced frames contain 106 channels.  Refer to the E7 RDS channel list for the names of these channels.  No decimation was performed on the raw data.

• LLO
 
There are 401 hours of E7 data at LLO.  The names of the reduced frames are of the form L-RDS_1_5-999999999-16.gwf, where 999999999 is the GPS time.  The correspondence between the location of the original full frames and that of the reduced frames is (from decatur):

/qfs2a/frames/Data0    to  Data167     <->     /qfs2c/rds/RDSA/Data0   to  Data167
/qfs2b/frames/Data0    to  Data167     <->     /qfs2c/rds/RDSB/Data0    to  Data167
/qfs2c/frames/Data0    to  Data47       <->     /qfs2c/rds/RDSC/Data0     to  Data47
/qfs2c/frames/Data48  to  Data64       <->     /qfs2b/rds/RDSC/Data48  to  Data64


 
• LHO

 
There are 410 hours of E7 data at LHO.  The names of the reduced frames are of the form H-RDS_1_5-999999999-16.gwf, where 999999999 is the GPS time.  The correspondence between the location of the original full frames and that of the reduced frames is (from fortress):

/export/qfs2a/frames/Data0  to  Data125     <->     /export/qfs2d/rds/RDSA/Data0  to  Data125
/export/qfs2b/frames/Data0  to  Data125     <->     /export/qfs2d/rds/RDSB/Data0   to  Data125
/export/qfs2c/frames/Data0  to  Data114     <->     /export/qfs2d/rds/RDSC/Data0   to  Data114
/export/qfs2c/frames/Data115  to Data125  <->     /export/qfs2a/rds/RDSC/Data115  to  Data125
/export/qfs2d/frames/Data0  to  Data15        <->     /export/qfs2a/rds/RDSD/Data0  to Data15
/export/qfs2d/frames/Data16  to  Data31      <->     /export/qfs2b/rds/RDSD/Data16  to  Data31

 
• Frame file sizes:

• LLO

reduced frame :   11.469 MB/frame  (75 channels)       =>     1.03 TB  for E7 run (401 hours)
full frame         :   44.534 MB/frame  (786 channels)     =>     4.02 TB  for E7 run
 
 
• LHO

reduced frame :   21.338 MB/frame  (106 channels)       =>     1.97 TB  for E7 run (410 hours)
full frame         :   78.169 MB/frame  (4601 channels)     =>     7.21 TB  for E7 run

Note:  At LHO, the channel H1:PSL-ISS_MC1_F was not found in the full frames, and thus is neither found in the reduced frames, for the time interval 693804128 to 694113056.  This is reflected in the decrease in the size of the reduced frames for this time interval.
 
 

• Non-existing frames:

Frames do not exist for the following GPS times:

• LLO
 
These time gaps occur in /qfs2a/frames/Data6/:

693610752  to  693610767     (16 seconds)
693610944  to  693610959     (16 seconds)
693613504  to  693613519     (16 seconds)
693613536  to  693613551     (16 seconds)

This time gap occurs between /qfs2a/frames/Data88/ and Data89/:

693909104  to  693944175     (35072 seconds)
