| Description: An abbreviated name or acronym for the specific channel of the HST instrument used for this observation. Here, "channel" refers to a distinct optical path used by one or more of the instrument's detectors. For HST instruments that do not have multiple channels, such as WFPC2, this attribute has the same value as the instrument_id attribute. |
