This data set, one of two originally archived on the physical volume
HAL_1003, has been reformatted into a single-data-set-volume format as
part of a general updating of legacy data to conform more closely to
contemporary data presentation. The original text of the HAL_1003
AAREADME.TXT file is below. Note that the data are now located under
a directory called "DATA", and only data for the present data set are
included. Documents and other files relevant to both data sets are
reproduced within each.

This data set collection contains MISCHA data for the International Halley
Watch Archive from Vega 1 which has been collected, archived, processed,
and prepared for this prototype CD-WO by teams associated with Space Research
Institute (Austria) and the PDS Small Bodies and Plasma Planetary Interaction
Nodes. This data set collection gathers additional material for the study of
Comet Halley and the solar wind.
Currently there are four groups of data:
Master files - flat file of magnetic field components (Bx,By,Bz,Bt,Bux)
with associated time in heliocentric solar ecliptic (H.SE) coord system
Survey files - flat file of magnetic field components (Bx,By,Bz,Bt,Bux)
with associated time in H.SE coord system
fbt1se files - flat file of magnetic field components (Bx,By,Bz,Bt,Bux)
with associated time in H.SE coordinate system. Data are collected
from 4 modes: DT, HS, T1, and T2- data averaged to 150 Sec sampling
fbt2se files - flat file as above except in only the DT, HS, T2 modes
The data files were submitted in both the binary and ASCII form. In the
former case, the data were converted to ASCII tables were appropriate.
The data were checked by IDL routine developed at the Small Bodies Node.
Documents give explanatory text, calibrations (Postsrcipt or MS Word or ASCII
with figures), and articles (digitized with permission by the Institute for
Space Research). All documents and labels contain an 80-byte fixed length
record, with a carriage return (ASCII 13) and line feed (ASCII 10) as the
last two bytes. All the tabular data files as well as those files in the
INDEX and DOCUMENT directories are formatted according to PDS standards.
An outline of the CD-ROM is shown in the table below:
/CATALOG/*.CAT Mission, host, instrument, data set and ref

/DOCUMENT/PROCESS/DATACONV/ Data conversion explanation and examples
/DOCUMENT/PROCESS/OFFSET/ Offset and spin information
/DOCUMENT/PROCESS/POSITION/ Position information for both phases
/DOCUMENT/PLOT/ Two sample plots of MISCHA data for Vega-1
/INDEX/ Index table for the data files
