Summary of changes:

ARF:

The ARF files were updated to be used with the latest version of the pipeline, which applies
various time-dependent corrections that had previously been implemented as "average" corrections
in the ARF.

VIGN:

The vignetting files were updated to include the "Crab corrections". There will be a memo drafted
detailing these corrections; at present there is a powerpoint presentation available via Huddle
(interface with Brian Grefenstette) that describes the vignetting corrections and performance.

DETABS:

The detabs CALDB fils are included to allow for the NuSTAR ARF generation FTOOL to account for
absorption at the detector plane. This previously was done by the user via the "nuabs" XSPEC
local model. With the inclusion of the detabs CALDB files and the additional modules in the
ARF generator, nuabs is no longer required by the user. The nu*detabs*002 files in the
20130509 patch are improvements on the nu*detabs*001 files contained in the 20130423 patch.
RMF Updates:

RMF:

Improved depth cut performance in FPMA Det 3 based on observations of the Crab. The RMF now more
accurately reproduces the observed Crab spectrum in both depth-cut and non-depth-cut cases.

INSTRUMENT:

Introduced a cut on all modes where the PSD sensors are out of calibration range "METGRID_FLAG".
HK Range files were updated to filter out events with METGRID_FLAG=1.
