Using HSpot to create PACS observations
Figure 6.25. Range spectroscopy, step 1 : Start PACS Range Spectroscopy AOT and select "SED Red"
range mode.
In the second step by clicking on "Add Range" button the "Range Id", "Reference wavelength" and
"Continuum flux density" optional parameters appear in enabled mode. The range Id is a mandatory
field, the other two are optional parameter and used for point-source continuum signal-to-noise calculation only. Accepting the default zero values means the Time Estimator will not perform S/N calculation.
Note
In SED mode it is not mandatory to add a range manually. If the range line is missing from the
PACS Range Editor then HSpot will apply default SED values.
