L3_LAT_ALT_DAY
Name
L3_LAT_ALT_DAY
Purpose
This routine displays one orbit of L3 data at a time. A movie can be
generated, or a single day, or a PS file. You can step through the
data orbit-by-orbit, or day-by-day but only for a given orbit.
Category
SNOE, image, movie
Calling Sequence
L3_LAT_ALT_DAY, Coord, YYYYDDD YYYYDDD1
Inputs
COORD: The coordinate system of the data, either 'geo' or 'mag'
YYYYDDD: The day to display.
Optional Inputs
YYYYDDD1: The last day to display in a MOVIE sequence
Keyword Parameters
ORBIT: Set this to the orbit number to view (0 through 15) if you
want to see 1 orbit per day. If not set, all orbits are viewed.
MANUAL: Set this to control the movie manually
,: prev day (<)
q: Quit movie
j: Jump to day
l: Toggle LOG mode
any other key: next day
LV: The large value of the data [ !SNOE.f.L3_lv ]
SV: The small value of the data [ lv / 20. ] used with /LOG only
PS: Set this keyword to produce a POSTSCRIPT image
CH: Set this to the desired channel to view [ 2 ]
LOG: Set this if the log of the data should be imaged
MASK: Set this to mask out part of the data (PMCs)
EXTRA=e is used for:
IMDISP: (INTERP, OUT_POS, etc. )
DEVICE: (FILENAME, BITS_PER_PIXEL, PORTRAIT, LANDSCAPE, etc. )
others...
Outputs
An image, or a PS file
Side Effects
Uses the PS device if /PS set. Uses the current WINDOW
Restrictions
Must be in a L3-type directory (needs NO_?_den_???.dat)
Example
To generate an image:
L3_lat_alt_day, 'geo', 1998079
L3_lat_alt_day, 'mag', 2002150, /LOG, /PS, /INTERP, FILENAME='foo.ps'
To watch a movie:
L3_lat_alt_day, 'geo', 1998079, 1999079, /LOG
L3_lat_alt_day, 'geo', 1998079, 1999079, /LOG, ORBIT=7
To step through:
L3_lat_alt_day, 'geo', 1998079, /MANUAL
L3_lat_alt_day, 'geo', 1998079, ORBIT=0, /MANUAL
