Summary
Please follow the starlist format descibed here.
We suggest to submit your starlist by using the
observer login page. Doing so will install your
starlist file into the directory
/kroot/starlists/web/username.
An observation with NIRES is guided with a visible guider mounted some 4 arcmin offset from
the slit. As
described before
, it is an optical guider mounted
on the same rotator as the instrument. Therefore, changing the
PA changes the region of the sky seen by the guider. It is
possible that for a given PA the guider will not find a suitable
guide star. In general, a star visible in the DSS would be
suitable for guiding. So if a specific PA is needed please check that a
suitable guide star is available. If not, then consider changing
the PA.
- log on on to the observer login page.
- After loading the starlist click on edit List (Non-AO)
- Select K2 NIRES as the instrument and NIRES as PO
- Click show guide star catalog. This will show a table for the possible guide stars. It will also display a DSS for the field. It has three labels: NIRES, REF and REFN. NIRES is the pointing origin for the slit. REF is the PO for the guider. The possible guide starts are circled in red.
- Change the PA by editing the pos Angle(deg) box. This is next to the K2 NIRES box. Click on Update Target.
- See how the guider field of view rotates as you change the PA.
- If you click on a guide star a green box appears. You
can select the correct PA so that the green box is inside
the REF blue square box.
- Unfortunatelly, this application does not enter
the position angle in the correct format for
Magiq. Please check the formatting
instructions
to enter
the rotator position and rotator mode correctly.
