Evan G. and I have restarted CW hardware injections, using the
old iLIGO actuation scheme, where the correction for the actuation
function is done directly, frequency by frequency, for each of
the 15 injected pulsars individually, without using a time-domain
inverse actuation filter. That filter is now no longer in the
path between H1:CAL-PINJX_CW and H1:CAL-PINJX_HARDWARE. We have
verified that the new envelope of the H1:CAL-PINJX_HARDWARE channel
is close to what it was before and that the spectral heights of
the injected signals look about the same (we don't expect perfect 
agreement). 

The injections will be left running for at least 24 hours, to verify
that the sidereal-day envelope agrees with what it was before,
within expectation, and that same-sidereal-time spectral snapshots 
agree reasonably well.

For reference, a new subdirectory O2test has been created in
the hinj Details/pulsar/ directory for this test and the
symlink RELEASE redefined to point to it. The only differences
between the files in O2test and O1test are the addition of
Evan's actuation function posted here and new in.N (N=0-14)
command files with the makefakedata actuation argument turned on.

Once we are satisfied the new injection actuation is working
as intended, the svn directories will be updated. One other
change I'd like to make is to use an actuation function file
that takes into account the extra time delay for the excitation
channel itself. Evan will consult with Jeff on approval for
that swap.
