CHANGE LOG FOR V4P1 (7-YEAR DATA) RELEASE
---------------------------------------
D.L.Larson, June 4, 2010
The diagnostic program test.F90 wsa updated to be consistent with the V4P1
release; and lines 660-665 of WMAP_7yr_tetbeebbeb_pixlike.F90, which write
debugging information to a file, were commented out to avoid problems with some
compilers. Neither change affects the actually likelihood function.
J.Dunkley, E.Komatsu, D.L.Larson, M.R.Nolta, May 27, 2010
** Two small bugs have been fixed, which involve the high-ell TT, TE, TB, and
point source power spectra:
1) The original computation of the TT spectrum used an incorrect monopole
subtraction which resulted in a small amount of excess power at high ell, and a
corresponding elevation of the best-fit residual point source amplitude.
Correcting the monopole subtraction reduced the high-ell power slightly which
produced a correspondingly lower residual point source amplitude, from 11.0 to
9.0 uK2 sr.
2) Due to a simulation configuration error, the TE fsky recalibration factor
used in version 4.0 was 1.049 instead of the factor 1.011 used in this version.

-- Patch to make the data directory selectable through an environment variable.
T. Kinser, Lawrence Berkeley National Laboratory, Oct 2008
This patch is available as a separate download from LAMBDA.
---------------------------------------
CHANGE LOG FOR V3 (5-YEAR DATA) RELEASE
---------------------------------------
J.Dunkley, E.Komatsu, D.L.Larson, M.R.Nolta, February 2008
** The 3-year data files and routines have been replaced by
the 5-year ones.
WMAP_5yr_tt_pixlike.F90
-- The resolution 3 option has been removed. This module supports
only the resolution 4. For a quicker estimation of low-l temperature
likelihood (with the same precision) the Gibbs sampling is recommended.
To use the Gibbs sampling (and disable pixlike option), set
"use_gibbs = .true." in wmap_options.F90.
** The following new routines have been added:
WMAP_5yr_tetbeebbeb_pixlike.F90
-- This module computes the low-l polarization likelihood of
TE/TB/EE/BB/EB spectra. To use this, compile the codes with
"WMAPFLAGS += -DUSE_LOWELL_TBEB" enabled in Makefile, and
call wmap_likelihood_compute(cl_tt,cl_te,cl_tb,cl_ee,cl_eb,cl_bb,like)
WMAP_5yr_gibbs.F90 [together with br_mod_dist.f90]
-- This module computes the low-l temperature likelihood by
using the Gibbs sampling. To use this, set "use_gibbs = .true."
in wmap_options.F90.
** The following new compiler options (see Makefile) have been added:
WMAPFLAGS += -DUSE_LOWELL_TBEB
-- enable the pixel-based polarization likelihood option for TB/EB at l=2-23
WMAPFLAGS += -DUSE_HIGHELL_TB
-- enable the master likelihood option for TB at l=2-450
-----------------------------
CHANGE LOG FOR V2P2P2 RELEASE
-----------------------------
M.R.Nolta, November 2006
WMAP_3yr_tt_pixlike.F90:
-- Sped up the TT pixel likelihood module by a factor of 10 using
signal-to-noise eigenvalue compression (suggested by Jon Sievers; see
http://lambda.gsfc.nasa.gov/product/wmap/dr2/likelihood_faster_v2p2p2/
for more details). To enable, set -DFASTERTT during compilation.
WMAP_3yr_likelihood.F90:
-- Minor bug fix; TE sanity check is now abs(TE)/sqrt(TT*EE)<1 instead of
TE/sqrt(TT*EE)<1.
-- Moved fisher matrix from the stack to the heap to fix crash when using the
XLF compiler.
WMAP_3yr_teeebb_pixlike.F90:
-- Added deallocation statements to fix crash when using the XLF compiler.
-----------------------------
CHANGE LOG FOR V2P2P1 RELEASE
-----------------------------
M.R.Nolta, October 2006
WMAP_3yr_likelihood.f90:
-- A beam error is now treated as a warning instead of an error. Warnings are
not fatal to a run; instead the correction is set to zero and the issue is
reported.
WMAP_3yr_util.f90:
-- New status variables were added to track warnings and to indicate whether or
not there were errors and/or warnings.
-- A subroutine was added to report warnings, and the error reporting subroutine
was modified to also report warnings.
