1.3 Non-HST Filter Systems


In addition to the HST instrument components, the graph table also supports various standard filter system passbands. The passband keyword string consists of the name of the system plus the passband name. An example of a passband observation mode string would be "COUSINS,I". If no system name is given for any of the UBVRIJHK bands, the defaults are Johnson UBV, Cousins RI, and Bessell JHK. For example, "v - r" will result in Johnson V minus Cousins R.

For a more detailed description of these filter systems, including the classification of photometric systems into "supported" and "unsupported", see Section 3.3.
