JUPLOC

Name

juploc

Purpose

Find and extract Jupiter in images and create PDS FITS headers on output.

Description

Calling Sequence

juploc,root,imnum, $
PATH=path, OUTPATH=outpath, PANG=in_pang, PSCALE=pscale

Inputs

root - String, contains the date root of the file name to be read.
imnum - Integer value or array of image number to process.
File names are root+'m.'+imnum (imnum converted to 3 digit string)

Optional Input Parameters

Keyword Input Parameters

BORDER - Border around Jupiter for extracted image (default=15).
LATITUDE - String containing latitude for observatory, this value overrides
the value expected in the header. Format MUST exactly match this
example: '+37:20:36.0'
LONGITUDE - String containing longitude for observatory, this value overrides
the value expected in the header. Format MUST exactly match this
example: 'W 121:38:12.0' (use E for East longitude)
ALTITUDE - String containing altitude for observatory, this value overrides
the value expected in the header. Format MUST exactly match this
example: '1290.0' (in meters)
PATH - Directory in which to look for data (default = current directory)
OUTPATH - Directory in which to write data (default = current directory)
PANG - Position angle of Jupiter's north pole on image, this is the
standard astronomical position angle measured eastward from
North but in this case, take the top of the image as "north"
and image must have the proper handedness on input.
PSCALE - Plate scale of image in arcsec/pixel. Default=0.5 but this
default is fairly meaningless. This needs to be the right
value or cropped image will be the wrong size.
AUTO - Flag, if true suppresses request for mouse confirmation.
Be careful with this, there is no clean way to interrupt
things if something goes wrong.
