Upload Table Instructions

The table upload feature finds positional matches with coordinates in an input source list. The input table file must be created on the client machine in ASCII format according to rules regarding formatting and column names.

Use the [Browse...] button to select the local table file for upload, or type in the file name. Enter the radius of the search region and select the required angular unit. If the search radius exceeds the maximum allowed value, 1800 arcseconds, or is <= 0 arcseconds, the Postage Stamp server will default to a value of 5 arcseconds.

Examples

\ Example of a circular search geometry table with ra and dec values
\EQUINOX = 'J2000.0'
|  name                  |  ra       |  dec       |  radius |
   M31                      10.684710    41.268749        10
   2MASXJ06111689-6609210   92.820389   -66.155838        50

\ Example of a circular search geometry table with glon and glat values
\EQUINOX = 'J2000.0'
|  name                  |  glon   |  glat   |  radius |
   M31                      121.174   -21.573        10

Detailed Table Format and Column Naming Rules

1.The Table File Name

No more than 9 characters, followed by ".tbl". Use only letters, numbers or underscores ("_").
Examples: Seyferts.tbl, MyListJ2k.tbl, LBD4_16A.tbl

2.Table Keywords and Comment lines

Keywords follow the FITS keyword=value model. The keyword names start with "\", followed by 8 characters, followed by an equals sign ("="), followed by the value. "\" followed by a space is treated as comment line. The comment line should have no more than 80 characters.

3.Table Header

The header lines are optional.

4. Column Names

Line 1 contains field (column) names separated by bars (|);

5. Datatypes

Line 2 contains variable types (real, double, int, char) separated by bars ("|") which must be aligned with the bars in Line 1 (i.e. | char | double | double | real | real |)

6. Data

The table can contain J2000 equatorial coordinates in decimal degrees with column names "ra" and "dec", or other user defined columns such as: Equatorial coordinates in another equinox or in sexigesimal format; Galactic coordinates; or, Ecliptic coordinates. To avoid confusion, the values should be aligned WITHIN the vertical delimiting bars in the header. Overlaps with a header bar is not allowed.

7. Missing Values (NULLs)

Missing values (NULLs) can be most easily handled by entering blanks (white space) or the string "null" in the numeric data columns (type int, real or double) to represent missing data.
