Uploading Lists of Targets
Using the
button, one can upload a file containing a list of astronomical object names
and/or positions. These object names and/or positions are then added to one's
form. Note: Any other required fields in the target/observation form
will still need to be filled out using the web interface. Alternatively,
after adding some targets, one can use the Save button to download a
plain text representation of the ARK form which one can then edit and
Reload into ARK.
The uploaded file should contain one astronomical object name and/or
position per line. (Blank lines and lines beginning with # are
ignored.) Each line should contain a comma-separated list of astronomical
name, longitude, latitude, and coordinate system. These four items may be
separated by vertical bar characters (|) instead of commas, if so
desired.
If the position is not specified, the object name will be resolved using
either the SIMBAD or NED name resolvers
(in that order). The coordinate system does not need to be specified in this
scenario either. If for some reason the astronomical object name cannot be
unambiguously resolved by SIMBAD and NED, the coordinates will be left
unspecified and the user must enter them explicitly.
Valid coordinate systems:
- J2000
- Equatorial FK5 system with equinox 2000.0 — If a position is specified without a coordinate system, the coordinate system will default to this.
- B1950
- Equatorial FK4 system with equinox 1950.0
- J####.####
- Equatorial FK5 system with an arbitrary equinox consisting of any
four-digit year and optional decimal portion
- B####.####
- Equatorial FK4 system with an arbitrary equinox consisting of any
four-digit year and optional decimal portion
- Galactic
- IAU galactic coordinate system introduced in 1958
