artsintfmagg − utility to aggregate interface matrix objects
in time domain


artsintfmagg [‐v] [‐i ifIndexList] [‐I ifIndexList]
             [‐h hours] [‐o] [‐q] outfile infile(s)

artsintfmagg is a utility that reads interface matrix
objects from ARTS files (infile(s)) and aggregates them in
the time domain, placing the resulting interface matrix
object(s) into an output file (outfile).  For example, you
may use artsintfmagg to aggregate 5‐minute interface matrix
data to 1‐hour interface matrix data.



‐v   The ‐v option causes artsintfmagg to print version
     information and exit immediately.

‐i ifIndexList
     The ‐i ifIndexList option may be used to select only
     data which contains an interface index attribute in
     ifIndexList.  In other words, the ‐i ifIndexList option
     lets you select data from particular interfaces or sets
     of interfaces.  ifIndexList may contain hyphens
     (indicating an inclusive range) and commas.  For
     example, ‐i 1,2,5‐8 would select data with an interface
     index attribute of 1, 2, 5, 6, 7 or 8.

‐I ifIndexList
     The ‐I ifIndexList option may be used to combine data
     which contains an interface index attribute in
     ifIndexList.  In other words, the ‐I ifIndexList option
     lets you aggregate data across a set of interfaces.
     ifIndexList may contain hyphens (indicating an
     inclusive range) and commas.  For example, ‐I 1,2,5‐8
     would aggregate all data data with an interface index
     attribute of 1, 2, 5, 6, 7 or 8.  The resulting
     aggregate objects will contain an interface index
     attribute of 0.

‐h hours
     The ‐h hours option may be used to specify the period
     of aggregation, in hours.  The hours argument accepts a
     decimal value to permit aggregation by fractional hour
     values.  When the ‐h hours option is not used,
     artsintfmagg will write a single interface matrix
     object for the entire time interval seen in infile(s)
     to outfile.

‐o   By default, artsintfmagg appends to the output file, so
     you may accumlate aggregate interface matrix objects in
     a single file over multiple invocations of
     artsintfmagg.  You may override this behavior with the









                             ‐2‐


     ‐o option.  This will cause artsintfmagg to overwrite
     the output file instead of appending to it.

‐q   By default, artsintfmagg prints a ’.’ for each
     interface matrix object it reads and prints a ’+’ for
     each object it writes.  You may suppress this behavior
     using the ‐q (quiet) option.
