Table C.21: SOFI img cal DomeFlats and SOFI img cal SpecialDomeFlats.
unlike the other templates where the offsets are defined along the RA and Dec, here they are defined
along detector rows and columns, and are entered into SEQ.OFFSETX.LIST and SEQ.OFFSETY.LIST.
Offsets are in arcsec.
Guiding is possible (defaulted to Star-To-Box) if SEQ.COMB.OFFSET is set to True (T) and if guiding
was started before the start of the template.
If SEQ.RETURN is set to True (T), the telescope slews back to its original position at the end of the
template. If not, the telescope is not moved.
Although it is possible to observe standard stars with any of the imaging science templates, using
this one is recommended because it sets up properly the header keywords necessary for the pipeline
data reduction of the standards.
In the next example (Table C.23) SOFI img cal StandardStar is used to obtain 5 images: the first
on the acquisition position and the others defined by the list of offsets. At the end you have an “x”
pattern.
