DESCRIPTION = "The header has 128 elements giving operation
mode, date of observation, time exposure, peltier
and CCD temperatures, etc. informations.
All relevant parameters are in the label as
keyword.
Examples: Time of each record (year,month,day,
hour,minute,second,centisecond) is given by the
elements HEADER_ARRAY[61:67*]. Peltier and CCD
temperatures are given by the elements
HEADER_ARRAY[50:51*] (*count from 1).
