Status of ENSDF Analysis and Utility Codes
(November 10, 1998)

Major Improvements

ENSDAT:

• Maximum Z is now defined up to 115.
• The ability to use commands on cards following a dataset has been added.
• Chemical symbols for Z's 104 to 109.

FMTCHK:

• Expanded allowed types of WIDTH's
• Expanded allowed mixtures of decay modes
• NUCID A and Z are checked against A and Z calculated from the parent and decay mode for decay data sets
• For adopted data sets with no PN record and any data set with option 6 on PN record, check for existence of one gamma with RI=100 for each set of deexciting gammas
• Upgraded to IUPAC symbols for Z>103 and added warning message for the old formalism

NSDFLIB: Modified to handle IUPAC chemical symbols between Z=104 and 109 inclusive. Extended allowed range of Z's from 112 to 199.

PANDORA: In case of unique parent/daughter JPI all mults must be valid

Minor Improvements

COMTRANS:

• Column footnotes were not capitailized.
• The comments data set did not terminate properly if the last section was a funding acknowledgement.
• The comments dataset had extra blanks in the comments section if the continuation cards began with them.
• 16- and 32-bit versions available for Windows/MS-DOS

ENSDAT:

• Multiplicative constants in intensity footnotes can now be given in exponential form if that is shorter.
• Partial updates to prepare for Y2K.
• HF was not placed correctly on the Alpha drawing.
• Usage of the % sign in the XREF field is allowed.
• Exponential parent branching value is now correct.
• The command GENCOM was missing.
• 16- and 32-bit versions available for Windows/MS-DOS

FMTCHK: Many - See http://www.nndc.bnl.gov/nndcscr/ensdf_pgm/utility/fmtchk/readfmtc.me for details.

NSDFLIB:

• Corrected error in IZEL when mixed alphanumeric symbol (e.g. "1S") passed to it.
• Changed IOVRFLW to IVRFLW for ANSI standard considerations

RULER:

• Corrected range error in OUT2ON
• Changed calls to VAX TIME/DATE routines to handle Y2K problem.

PANDORA: Ignore blanks following "FL="

TREND: Illegal column footnote when given as the final table comment caused the program to bomb for gamma tables with intensity flags given.

MS-DOS Versions

With the exceptions of COMTRANS and ENSDAT, the MS-DOS versions of the ENSDF analysis and utility codes maintained by the NNDC are up to 4½ years behind the OpenVMS and ANSI-standard versions. The MS-DOS versions will be brought up to current levels by the end of 1998. The following changes are planned in this update:

• DEC Visual FORTRAN will be used instead of Microsoft FORTRAN 5.1.
• Distribution will only be done through the World Wide Web and anonymous FTP except in special circumstances.

Codes No Longer Maintained

With the advent of the program ENSDAT, the programs PREND and TREND are no longer being maintained and upgraded.

Codes from Other Centers

No upgrades have been received for distribution from the Isotopes Project, LBNL (GABS, GAMUT, SPINOZA) since October, 1993. The program DELTA from Lund University, Sweden has not been upgraded since April, 1993; however, this code does not use the ENSDF format and probably needs no upgrades.

Projected Upgrades

All Codes:

• Implement ENSDF format changes agreed to at the Vienna NSDD meeting.
• With the exception of COMTRANS, FMTCHK, and ENSDAT, the codes need to be checked for the change in chemical symbols for the high-Z elements.

ALPHAD: Investigate numerical methods of calculating non-Gaussian probability distributions.

LOGFT:

• Add coding for properly calculating higher orders of forbiddenness (3^rd and 4^th).
• Investigate calculating log ft's for completely ionized atoms.

RadList:

• Bring the current distributed version (5.5, Oct. 1988) up to the present in-house version (5.7f, Oct. 1998).
• Produce 32-bit version for Windows/MS-DOS.
