Use of the executable "decipher_s055"
Returns 7 files per tape file "s055image"

Content of s055image_load:
list of the numbers of data (read) of every kind

Content of s055image_line:
12 columns of values 
11 lines correspond to one line by one detector + 6 at beginning + 6 at end
OFF detectors are flagged by 132 values of 16384
missing data are flagged by 32767
Structure:
  line 1 of detector 1
  line 1 of det 2
  line 1 of det 3
  line 1 of det 4
  line 1 of det 5
  line 1 of det 6
  line 1 of det 7
  line 2 of det 1
  line 2 of det 2
  ...

Content of s055image_rast:
no distinction between rasters, but one image consists of 132x60 values
these values follow exactly the order of the fiche
one record = one quarter of one image
Structure:
  lines   1> 60 = 1st raster = ( 1>15)x(132>1) of image 1 
  lines  61>120 = 2nd raster = (16>30)x(132>1) of image 1 
  lines 121>160 = 3rd raster = (31>45)x(132>1) of image 1 
  lines 161>240 = 4th raster = (46>60)x(132>1) of image 1
  lines 241>300 = 5th raster = ( 1>15)x(132>1) of image 2
  ...
detectors OFF do not return any raster ! => no fixed length
  
Content of s055image_spec:
12 columns of values
2 lines (=24 values) per second
there are 2004 values (167 lines) per spectrum (as indicated in the ID record)
Blanks are filled either with zeroes or 32767s
several spectrum on different detectors will be as followed:
  values of det1
  values of det2
  values of det3
  etc
detectors OFF are ignored (do not return any spectrum)
