Overlaying various labels

A star symbol can be displayed at specified coordinates on the output graph using the STAR keyword. The syntax is STAR=[RA,Dec] or STAR=[[RA_1,Dec_1], [RA_2,Dec_2], ...]. Note that the input coordinates must be in decimal degrees and that the assumed epoch is the one specified by the astrometry information of the reference input image. In order to be certain that the list of coordinates is correctly interpreted, it is advisable to simultaneously use the EPOCH keyword. (see section 3.2). (See Fig. 6)

A title is displayed at the top of the graph (the default title is ISOCAM). The user may modify that using the TITLE keyword. The IDL syntax for special characters is assumed. (See Fig. 7)

By default, the labels ISOCAM Interactive analysis and ESA/CEA-Saclay are included at the bottom of the display window. This can be avoided using the /NOCOPYRIGHT keyword. The north-east orientation is also displayed when RADEC=0. This can be turned off as well using the /NONORTH keyword. (See Fig. 8)
