Subject: E11 NO_DATA, NO_RDS, and NO_L3RDS flags

Hi Keith, Ben, Greg, and Stuart,

I have compared the lists of E11 science-mode segments with the available
data in the /archive filesystems at Hanford and at Caltech.  Note that the
Caltech /archive only has L1 and L3 RDS data from the E11 run so far, not
the full-frame data.

There is one RDS file which exists at Hanford but is missing from Caltech:
H-RDS_R_L1-785096064-64.gwf .  Can someone please copy that to Caltech?

The science-mode segment lists include some segments which are outside
the official time span of the E11 run.  The raw data was not kept for
most of this "extra" time, but there is still "extra" raw data in the
range 784713952-784725408 at Hanford, which is during an H2 science-mode
segment.  The H2 NO_DATA flag times listed below assume that this "extra"
raw data will be DISCARDED, i.e. not permanently archived at Caltech.

With those assumptions, here are the data quality flags:

H1 data which should have NO_DATA flag:
   Segment  87 : 785318432-785318436
   Segment  88 : (entire)
H1 data which should have NO_RDS flag:
   Segment  88 : 785318688-785342591
H1 data which should have NO_L3RDS flag:
   Segment  88 : 785318688-785342591
H2 data which should have NO_DATA flag:
   Segment   1 : (entire)
   Segment   2 : (entire)
   Segment 115 : 785318432-785320673
H2 data which should have NO_RDS flag:
   Segment   1 : (entire)
   Segment   2 : (entire)
   Segment 115 : 785318688-785320673
H2 data which should have NO_L3RDS flag:
   Segment   1 : (entire)
   Segment   2 : (entire)
   Segment 115 : 785318688-785320673

Note that no data is missing during science-mode segments within the
official span of the E11 run!
