Pipeline Module Specifications

gentargs

Module Version
	0.8	10 III 2010

General Description
	gentargs generates the lists of target latitude and longitude centers
	and tracking ranges for a selected time for the synoptic pipeline.
	Special flags generate lists needed for other pipelines,
	in particular the MDI "dense-pack" and "structure-pack" grids.
	The module output is in the form of lines of text sent to stdout
	and expected to be parsed by a script.

Status
	This version has been superseded by Version 0.9

Usage
	gentargs [-flags] time= TargetTime
	
Flags
	-d	generate latitude and longitude targets for the MDI "dense-pack"
	-M	use SOHO ephemeris for B0 calculation or conversion of time parameter
		in calendar-clock format to Carrington time
	-s	generate latitude and longitude targets for the MDI "structure-pack"
	-v	run verbose

Parameters
	time	The target time for the grid-point calculation. The time
		can be specified in either calender-clock (YYYY.MM.DD_hh:mm:ss)
		notation or in CR:CL (Carrington rotation plus central meridian
		of epoch) form; the latter is recommended. The time will be rounded
		to the nearest one appropriate for the grid spacings requested,
		2.5 deg for the HMI synoptic set, 15 deg for the packs.
		Default: current time minus 120 deg of Carrington rotation.

Bugs in current version
	Invocation of the -M flag to use SOHO ephemerides requires the presence of
	appropriate ephemeris tables at a fixed system disc location; if they are
	not present, the earth ephemeris will be used. However, the ephemeris
	information is only used for converting time parameter values in calendar-
	clock format to CR:CL format, and for calculation of B0. The value of B0
	only matters for the definition of the HMI synoptic pipeline set, not the
	dense-pack and structure-pack sets appropriate for MDI. As long as queries
	to the database for the input to mtrack are based on central meridian
	longitude rather than time, this should be of no concern.

	There may be problems parsing regular calendar-clock time strings; use of
	the CR:CL format for the time value is recommended.
