46 | ; @keyword CONTINTERVALLE |
---|
47 | ; When CONTOUR is activated, it is the value between 2 isolines |

---|
49 | ; in this case, does not control colored isolines in color anymore. If there is noone |

50 | ; specified min, we choose a contour min which goes well with the specified interval! |

78 | ; 'U','T','V','W' or 'F' |

83 | ; Value of an interval between to isoline. If there is none specified min, |

---|
85 | ; If this keyword is not specified, we trace 20 isolines from the min |
---|
86 | ; to the max. |
---|
87 | ; Comment: When CONTOUR is activated, INTERVALLE only specify the interval |
---|
88 | ; between 2 colored isolines. To specify the interval |
---|
89 | ; between 2 isolines traced by a trait, use CONTINTERVALLE. |

104 | ; MAP=[P0lat,P0lon,Rot]. For the description of these 3 values (see the online help of <proidl>MAP_SET</proidl>). |
---|
105 | ; /MAP: In this case, map is automatically calculated have the value: |
---|
106 | ; map = [0, (lon1+lon2)/2., 0] |
---|
107 | ; Comment: A good way to choose the type of the projection we want to do is to have a look at IDL demo: |
---|
108 | ; IDL> demo |
---|
109 | ; Then choose "earth sciences and mappinA"g |
---|
110 | ; Comment2: By default it is a cylindrical projection which is done (with or without the keyword map). |
---|
111 | ; If we want an other projection, MAP must be activated and we have to add the keyword: /nom_projection. |
---|
112 | ; For example, for a polar projection centered on the south pole: |
---|
113 | ; IDL> domdef,-180,180,-90,-45 |
