The recommended method to find exposures utilizing certain instrument modes and/or
filters is to define the desired instrument configuration in the XSA interface.
The uncalibrated files (ODF, Section 4) do not contain the information
about instrument modes or filters except for some non-scientific modes, see
Sections 4.1.4 and 4.1.8.
The SAS task odfingest (with the parameter set findinstrumentmodes=yes
which is default) produces a SAS summary file (*SUM.SAS, see
last row in Table 1) that contains the names of instruments
and filters which are then written into the file headers of SAS and pipeline
products (such as events files) using the header keywords SUBMODE
(DATAMODE for OM) and FILTER, respectively.
In this section, the names of instrument modes that can be found in
the *SUM.SAS file (and consequently in the file headers of high-level
science products) are given for scientific modes and for non-scientific modes.
For the latter, no pipeline products are produced and the only way (apart from
an XSA search) to identify the instrument mode and filter for a given exposure
is the *SUM.SAS file.
