(I) General Notice on Service Observation with SWIMS
Only imaging observations are available. Please note that nonsidereal
tracking mode is not available.
Those who plan to submit the service program proposal should make a
detailed observing plan including overheads, and confirm that the plan
fits
in the 4-hr limit of service program.
The overheads that should be considered are target acquisition
(2-3min), readout time (see SWIMS web page) and additional time for
dome flats.
Please describe the plan at the beginning of the observation file.
(II) Required Information in ASCII format
Please submit a plain ASCII text file.
The following information should be provided for each target and
observing mode, including calibration standards.
1. Target/field name
2. Magnitude/range of magnitudes in a specified band
3. Are photometric conditions necessary? (Yes/No)
4. What is the maximum acceptable seeing size in arcseconds?
5. Coordinate of the pointing
5-1. Right ascension in format HHMMSS.SSS
5-2. Declination in format (+/-)DDMMSS.SS
5-3. Equinox of position in format YYYY.Y
5-4. Position angle in degrees
Note that as the focal plane of SWIMS is covered by two 3.3'x3.3'
FoV array detectors separated by 15arcsec,
an object at the pointing coordinate will fall within the gap an
will not be visible.
The position angle is defined to be zero when the two detectors are
arranged along right ascension.
6. Filter settings for observation.
6-1. Filter for blue arm
6-2. Filter for red arm
As SWIMS is a two-color simultaneous imager, filters for both the
blue (0.9-1.4um) and red (1.4-2.5um) arms should be
specified.
7. Exposure parameters for each setting
7-1. Individual exposure time and number of Fowler readout for each filter.
Note that in most cases including narrow-band imaging, background
limited condition can be achieved with
enough-long exposure time, such as 120sec.
7-2. Number of dithering points and dither radius
Note that the dithering points are arranged evenly on a circle with
a dither radius.
7-3. Number of exposures at each dither position, for both the blue
and red arms.
If you need any other calibration data, please describe here (note
that twilight flat is not available for the service observation). Then
add the following information.
7-4 Number of dithering loops to be executed
Note that otal exposure time is (Number of dithering loops) x (Number
of dithering points) x (Individual exposure time)
8. Requests for calibration
As a standard set of calibration data, following frames will be
taken in the evening or morning of the observing night while the dome
is closed.
- dome flat (5 frames with the maximum count below 20000 ADU)
- dark (10 frames with 1.5sec exposure)
If you need any other calibration data, please describe here (note
that twilight flat is not available for the service observation).
9. Special requests for observation (if any)
(III) Finding charts
Finding charts should be attached for each targets.
Please show the target name, the orientation (north and east), and the
scale in the chart. In addition, the following information should be
added .
1. Show the SWIMS FOV (6.6' x 3.3') on the chart.
If you intend to submit more than 2 finding charts, please compile
them into one PDF file.
A-1. Number of finding charts contained (number of pages of the PDF file).
A-2. Give information 1 to 5 below for each of the finding chart.
1. Page number
2. Object name
3. Size of the chart
4. Orientation of the chart (north and east)
5. Other comments (if any))
