*Summary of important changes


The release of this sub-version is necessary for correcting some SASv16.0 issues
related to source detection, detailed below.



The changes introduced in this release are the following:


- eboxdetect:  correction of a  bug introduced  with SASv16.0  that made
 some obvious sources  to be missing in the EPIC source lists of a few
 observations.


- emldetect:  reduction  of  the  number  of  spurious detections,  and
 solution to the problem of missing valid detections close to chip gaps
 or very far off-axis.


- especget: improvement of the performance for large background regions.


- eimageget: solved a problem with tangential plane projections in large
 images.


- eimagecombine:  significant  reduction  of  the usage of  disk  space
 through compression of intermediate files.


We took also the opportunity to include a minor upgrade of esas, the task collection for
analysis of extended sources. In addition all the six packages corresponding to the patch
issued in February are also contained in this release.


This version of SAS is released  in two 64-bit binary versions for Linux
(RHEL  6.8  and Ubuntu  16),  and  two for  Mac  OS  X (El Capitan  and
Sierra).  The versions  released have  been tested  to run  correctly on
several other platforms.

* Detailed list of changes between SAS 16.0.0 and SAS 16.1.0

A detailed list of all upgraded tasks wrt SAS 16.0.0 follows, the corresponding
ChangeLogs are further below:

ChangeLog

Version 4.27.4 - 2017-01-16 (IT)
--------------
	+ ebox_io.f90: Fixed two typos in the new subimage coordinates of the
	  detection masks.
	+ release memory for CAL pointers
	+ increased some internal array sizes

Version 4.27.3 - 2016-12-03 (IT)
--------------
	+ Removed debugging comments from the code after testing v4.27.2.
	+ Updated documentation: Parameter withoffsets=yes (obsolete
	  eident offsets) yields a warning; no other effect anymore.

ChangeLog

Version 4.11.2 - 2017-06-22 IT
------------
	+ eexpmap_mod.f90: More pointers need to be nullified and
	  badpixtype has to be initialized with zero for gfortran.

Version 4.11.1 - 2016-11-14 (AI)
------------	
	+ (src/eexpmap_mod.f90) Initialization to null (at declaration statement)
	of those pointer that will be used by the CAL to avoid seg fault in gfortran.

ChangeLog

Version 0.8.1 - 2017-06-19 (mjf)
--------------------------------
- (src/eimagecombine.sh): compress intermediate files that are not re-used
  immediately but kept until the end (to reduce used disk space significantly)
- (test/eimagecombine_test_1): check for existence of compressed files

Version 0.8 - 2015-12-08 (nclerc)
---------------------------------
- add consistency check on SUBMODE for each image/exposure/band

ChangeLog

Version 0.7 - 2017-06-19 (rds/mjf)
----------------------------------
- (src/eimageget.sh): changed from "attcalc" to "attcalc2" projections
- (DEPEND): added attcalc2-1.3

Version 0.6.1 - 2017-01-21 (mjf)
--------------------------------
- (doc/eimageget_description.tex): minor editorial changes
- (doc/eimageget_description.tex): adapted link to new cosmos web structure
  (SPR-7416)

ChangeLog

Version 7.1 - 2017-05-29 (IT)
-----------
	+ New algorithm to determine the subimages. Cf. eboxdetect.
	+ Initialized some more arrays with zero for gfortran.
	+ emldata.f90: renamed event to events and event_type to
	  events_type, just to be on the safe side. event and event_type has
	  been introduced in iso_fortran_env (which we are currently not
	  using).
	+ emldetect_mod.f90, call to mlout: argument rawflag has to be
	  addressed according to parameter withrawrows; value true
	  accidentally remained from the test phase (SPR-7431).


Version 7.0.3 - 2016-11-08 (IT)
-------------
	+ fftpsf.f90: Sloppy indexing caused occasional segmentation
	  faults, in particular if emldetect is compiled with gfortran.
	  Also make sure that arrays are initialized with 0 for gfortran
	  compatibility. Fixes SPR-7405.

ChangeLog

Version 8.76.1 - 2017-01-16 (MJF)
---------------------------------
- (src/epchain): activated parameter "applyfilter" [epnoise]
closed SPRs:

- (config/epchain.*): as above
- (doc/epchain_description.tex): as above

-------------------------------	
- (src/epexposure_mod.f90) Initialization to null of pointer that is passed

-------------------------------
