The table upload feature reads coordinates and optional parameters from an input table. Only the coordinate fields are required; all other parameters default to what is specified on the Main FinderChart page unless specifically included in the table. The name of your upload table can be typed in directly or selected using the [Browse...] button.
The input table file must be created on the client machine and the format is quite flexible. The following two paragraphs provide formatting guidelines and helps for ensure your table be successfully uploaded.
Most of IRSA's services allow users to enter single objects or coordinates into a web form, or they can upload a file containing multiple objects and coordinates. The latter method is called "Table Upload," for which IRSA accepts four ASCII table formats:
There are two ways to ensure your tables will work with IRSA's services:
Example Test Tables:
Example 1: all input columns are specified; download example1.tbl
|objname| ra | dec |csys|equinox|size| flip|reproject|grid|marker| survey | M51 5.0 false false 1 1 [DSS] [2MASS] M109 5.0 false false 1 1 [SDSS] [DSS] [2MASS] M101 -125.0 -89.0 equ j2000 3.0 false true 1 0 [2MASS]
Example 2: a list of ra and dec positions, all other parameters are taken from your settings on the main FinderChart input page; download example2.tbl
| ra | dec | 13h29m52.37s +47d11m40.8s -125.0 -89.0 07 46 42.56 +20 00 32.1 240.0 32.0 116.67733 20.00892 318.99 -16.61
Example 3: a list of object names; download example3.tbl
| objname | m101 m51 m31
Example 4: selected columns are used; download example4.tbl
| objname | ra | dec | size | flip | M101 4.0 false -125.0 -89.0 3.0 true
The objname can be any name resolvable by NED or SIMBAD. This field is required but will be overridden if "ra" and "dec" fields are also present.
These four fields make up the object string to be parsed by IRSA's lookup service. "ra" and "dec" can be specified either in degrees or in sexigesimal; if "csys" and "equinox" are not specified, they default to "equ" and "j2000". The acceptable "csys" values are "equ", "ecl", "gal", and "sgal". The acceptable "equinox" values are "j2000", "b1950". "ra" and "dec" are required only if objname is not present.
This is a double precision number specifying the size of the image cutout in arcmin. This field is optional; it defaults to the FinderChart main page value which is set to 5.0 arcmin initially.
This optional field is either "true" or "false" specifying whether the image be displayed with East to the right ("true") or East to the left ("false"). North is always up. The initial default value is "false".
This optional field takes "true"/"false" value specifying whether to reproject the image pixels to a uniform scale and orientation. The initial default value is "false".
An optional integer specifying whether to draw grid on the postage stamp image on the result page. The default is "0" (no grid).
An optional integer specifying whether to put a marker at the input coordinate on the postage stamp image on the result page. The default is "1" (show marker).
This is a string specifying the datasets to be processed.
Dataset's names are enclosed in brackets '[' and ']' and
separated by blank space. If this column
does not exist, your selections on the main page are used.
Example: [DSS] [2MASS]
