Synopsis

Calculate the electric field and other parameters from convection map data.

Options

`--help`	print the help message and exit.
`--version`	print the RST version number and exit.
`-vb`	verbose. Log information to the console.
`-old`	the input file is a `map` format file.
`-old_aacgm`	uses the older AACGM software and coefficients. The default is to use AACGM-v2.
`-sd yyyymmdd`	extract starting from the date yyyymmdd.
`-st hr:mn`	extract starting from the time hr:mn.
`-ed yyyymmdd`	stop extracting at the date yyyymmdd.
`-et hr:mn`	stop extracting at the time hr:mn.
`-ex hr:mn`	extract an interval whose extent is hr:mn.
`-s step`	skip step number of records between each record extracted.
`-l latmin`	set the lower latitude of the grid to latmin degrees.
`-mlt`	include the magnetic local time in the output.
`-p`	include the potential in the output.
`-v`	include the derived velocity int the output.
`name`	filename of the `cnvmap` format file to process. If this is omitted, the file is read from standard input.

Description

Calculate the electric field and other parameters from convection map data.

The electric field data is written to standard output.

Examples

maptoefield -old -l 50 20050830.map > 20050830.efield

Calculate the electric field down to a latitude of 50 degrees from the file "20050830.map". The electric field data is stored in the file "20050830.efield".

maptoefield -p 20040830.cnvmap > 20040830.efield

Calculate the electric field and potential from the file "20040830.cnvmapmap". The electric field data is stored in the file "20040830.efield".
