#- Abstract
#
#  This file contains UNIX c- or tc-shell aliases providing short cuts
#  for the common time conversions supported by SPICE's CHRONOS
#  utility, applicable to MER. These aliases are for the MER-A rover.
#  
#  Majority of the MER-A time conversion aliases have form:
#  
#     from2to.a
#  
#  where [from] and [to] is any of the following time system/types:
#   
#     Acronym       Description
#     ---------     --------------------------------------------------
#     lsta          MER-A Hybrid (approximate) Local Solar Time (LSTA)
#     ltst          Local True Solar Time (LTST)
#     scet          UTC Spacecraft Event Time (UTC SCET)
#     ert           UTC Earth Receive Time (UTC ERT)
#     sclk          Spacecraft on-board Clock (SCLK), byte-based
#     sclkd         Spacecraft on-board Clock (SCLK), decimal
#  
#  and [.a] designates for MER-A. For example:
#  
#     lsta2scet.a   from LSTA to UTC SCET for MER-A 
#     scet2sclk.b   from UTC SCET to SCLK for MER-B
#  
#  Aliases are also provided for the following "special" conversions:
#  
#     scet2ett.a    between UTC SCET and UTC Earth Transmit Time (ETT)
#     ett2scet.a
#     
#     scet2et.a     between UTC SCET and Ephemeris Time (ET) expressed 
#     et2scet.a     as ephemeris seconds past J2000
#  
#     scet2doy.a    between UTC SCET in month/day and UTC in DOY formats
#     doy2scet.a
#  
#     sclk2hex.a    between SLCK in decimal and hexadecimal
#     hex2sclk.a    representation
#  
#     scet2lsun.a   computes L-sub-S for given UTC SCET
#  
#     scet2lt.a     computes one way light time for given UTC SCET
#  
#     scet2pst.a    computes PST and PDT for given UTC SCET
#     scet2pdt.a    
#
#     scet2pstert.a computes PST/ERT for a given UTC SCET
#
#     scet2pdtert.a computes PDT/ERT for a given UTC SCET
#
#  Two auxiliary aliases are provided to display kernels used by CHRONOS:
#
#     chronos.sclk.a       displays original SCLK name
#     chronos.kernels.a    display all kernels used by CHRONOS
#
