Plot/Contour NLDN lightning data
NLDNDISP parm map time day
| parm | LIG, LIG-, LIG+, SGNL, MULT | |
| map | mnemonic | any map mnemonic defined in MAP context table |
| OLAY | navigation from image; no map drawn (def) (same as NAV=C) | |
| SAT | navigation from image; no map drawn | |
| DEF | Define map using LAT, LON, SLAT, SLON keywords | |
| time | reference time (default = current) see INT= keyword for time span | |
| FRAME | plot data with same time as navigation frame | |
| day | Reference day (default = current) | |
Searching
| INT=int rel | Data window time interval [HH, HH:MM, HH:MM:SS] and relation of interval to time (default = 00:30 C - 30 minutes centered over time) | |
| C | centered, | |
| L | less than | |
| M | more than | |
Map/Navagation
| CMAP= | Base map color (default = 8) |
| ELE=min max | Minimal and maximal element extents (default = frame size dependent) |
| LAT=min max | Minimal and maximal latitude extents |
| LIN=min max | Minimal and maximal line extents (default = frame size dependent) |
| LON=min max | Minimal and maximal longitude extents |
| NAV= | Frame to use for navigation; specify a frame number or C for current frame (default = C); no map is drawn; you cannot use this keyword unless the default is used for the map parameter |
| PRO= | Map projection (CONF,MERC) [default = #SYS(899)] |
| SLON= | Normal longitude for CONFormal projection |
| COL= | Graphics color level of plotted data (default = next available) | |
| GRA= | Graphics frame number to display output (default = current) | |
| GU= | Enhancment to associate with frame | |
| LAB=text color ele size |
Label ext, color, location and size for title |
|
| text | title's text; 72 characters maximum; specify X without quotes for default text (default = computed) | |
| color | graphics color level of title (default = plot color) | |
| ele | beginning TV element to write title (default = left side of the frame) | |
| size | size of labels (pixels) (default =plot dependent) | |
| LSI= | Plot annotation size (default = 1: LIG-, LIG+, LIG; 6: SGNL & MULT) | |
| OUT= | PLOt or LISt output (default = PLO) | |
| SYM= | Plot annotation symbol (default = polarity dependent: PLUS,MINUS) choose from: SQUARE, PLUS, MINUS, WPLUS, BOX, CIRCLE, TRIANGLE, DIAMOND, PFLASH, NFLASH, PBOLT, NBOLT | |
| SF=YES | Displays image/graphics frame (default = NO) | |
Time is the reference time of a time interval; the length of the time interval is specified by INT= keyword. The value of INT= must be specified in a valid McIDAS time format. Use the rel parameter of INT= to specify the relation of INT to time.
