        -Correct the decay from 809.907 to the ground according to gamma input in DDEP pdf table.
         Info is missing in ENSDF. Correction to solve  the bug 1967.
        -Correction of gamma intensities from level 1040.536 according to input ENSDF file from DDEP.

5 September 2017 L.Desorgher
---------------------------
 Correction of transitions for floating levels in last 60 files.

13 July 2017 L.Desorgher
---------------------------
 Correction of transitions for floating levels in more than 300 files.

04 April 2017 V.Ivantchenko
---------------------------
 Old data removed, correlated_gamma files moved to the main directory

21 February 2017 Desorgher
-------------------------
 Correct the correlated_gamma files z64.a148,z64.a149,z64.a150,z81.a194 for problem of order of level
 index, reported by V. Ivantchenko.
 
1 February 2017 Desorgher
-------------------------
 Correct all the correlated_gamma files for the uncorrect setting of the multipolarity E0 as -1.
 No we  consider E0,E1,M1, as 1,2,3,..... The value of 0 is for unkown.

19 December 2016 Desorgher Laurent 
--------------------------------------------------------------  
 Update total internal conversion coefficient  of z90.a234 with DDEP data for U238 decay.
 Update total internal conversion coefficient  of z91.a234 with DDEP data for TH234 decay.
 Still need to correct partial ICC coefficient. Correction are done only in correlated_gamma_files.

 Checking of the format has been added in the python test suite.
-Remove PhotoEvaporation3.2 z*.a* files
-Add explode files z*.a*  from z* files.
-Correction of few gamma intensities in z6.a12, z16.a33,z17.a42,z34.a76,z38.a95,z38.a97,
           z41.a88,z56.a129,z74.a187

 16 September 2016 Laurent Desorgher         PhotonEvaporation4.0
-----------------------------------------------------------   
-Merging in the same database of the PhotoEvaporation3.2 z*.a*.txt files and the 
 new photoevaporation data files.
 The new data files are updated with  floating levels, multipolarity and mixing ratio data.
 The new files are in Z*.txt files.
 The README for the new data is the file README-LevelGammaData_Extended.
 

 6 November 2015 Dennis Wright         PhotonEvaporation3.2
-----------------------------------------------------------
- package Laurent Desorgher's new version of photon evaporation database
  which is meant to be consistent with the 4.3 version of the radioactive 
  decay database.  It is also formatted to remove scientific notation
  where possible and to remove trailing zeros. 
 
19 February 2014 Dennis Wright         PhotonEvaporation3.1
-----------------------------------------------------------
- contains Laurent Desorgher's corrections of of +X, +Y, ... levels for
    compliance with latest isomer list
- problem report 1565: propagate bug fix in NUDAT2 to PhotonEvaporation:
    212Bi (z83.a212, line 8), change strength of gamma transition
    (415.272 keV to ground state) from 4.4 to 0.4. 

3 September 2013  Laurent Desorgher    PhotonEvaporation3.0
-----------------------------------------------------------
