Corrections in FIDARC by A. Filippi   
======================

**general purpose updates**
- REAGEO: check of He bag gas, printout of the He percentage of the air/He 
          mixture (HELEAK flagged)
- GENINI: new validity time ranges for x(t) tables with new voltages
- DCHDEC: new validity time time ranges for cosmic rays runs
- CONSINIT: eliminated -MCARLO cmz flag
- XTRCH:  inserted new x(t) tables for LMDC's: voltage dividers moved:
          xt14 B=1 He 62% isobutane 32% -3400 V +1850 V
          xt15 B=0 He 62% isobutane 32% -3400 V +1850 V
          xt16 B=1 He 62% isobutane 32% -3400 V +1900 V
          xt17 B=0 He 62% isobutane 32% -3400 V +1900 V
          
 **read dst update**
To align the output ntuple to the one produced by FILLGENHYP, the geometry file
must be read, and readdst procedure must be aligned with proper calls to geant 
and zebra init routines. Check of geometry files to be read when multiple files
are processed is implemented.
- GENECDE:  update of READNTU common for readdst output ntuple
- GUOUT: transfer in DST bank structure the HEAD part of RDT containing info on
the geometry to be read 
- OPEFIL: check of filenames for multiple run chains
- DSTUPK: update to read the HEAD record in DST file, hosting information on 
geometry file to be read (MCARLO data - for real data the unix time is enough 
to use the correct geometry).
- USWORK: alignment of code to write the output ntuple (333), equivalent in its
          basic form to ntuple 127 + information on ISIM hits. SHORT flag code 
          implemented
          proper geometry file read for each DST file processed
- UHBINI: alignment of header of 333 ntuple with 127 hype one
- MAIN: zebra init

WARNING: don't compile fidarc using the RDST flag - reset it after readdst 
compilation, if fidarc rebuild is needed.

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

 - Correction of event zero decoding of drift chambers in READ_LIB (E. Botta)
 
 - Other corrections in DCHDEC and CONSINIT (F. de Mori)

Corrections in FIDAMC  (76 lines by A. Filippi)
======================

**general purpose updates**
- GENECDE: correction of 6Lithium nucleus mass


**HELEAK flagged code update**
Purpose: to use for the gas inside He chamber a realistic He/air mixture 
definedby weights (IN VOLUME) provided by HELK data card in fidamc.dat
- UGFFGO: definition of HELK key
- UGMATE: check of input HELK value. If provided outside the realistic range 
	  [0,1], the default value He 95% air 5% is taken; if not provided 
          the default value (He 100%) as in the case without HELEAK flag is 
          taken
- FIMCDAT/FIDAMC: new fidamc.dat with HELK card HELEAK flagged. HELK 1. 
          (100% Helium) is the default.

**readdst update**
- FIMCCOM/REBUILD_RDST: update to link SLDIST deck
- FIMCCOM/REBUILD_RC: reset rdst flag in case it's already active
