Create a User defined Source Table

 

Some applications in source detection need coordinate input in form of a table file. Such a table can be created and modified in one single command.

   
WRITE/RADEC_TABLE user_tab RA DEC [row]

 

• user_tab is the name of the user defined table with the columns :RA_DEG and :DEC_DEG specifying the right ascension and declination of a source position in degrees. If it does not exist (or if row=0, the default) then user_tab will be created.
• RA is the right ascension of a source, specificied as decimal degrees or as hours, minutes,seconds. It can also be specified with crossreference RA=.
• DEC is the declination of a source, specificied as decimal degrees or as degrees, minutes,seconds. It can also be specified with crossreference DEC=.
• row is the number of the row of the table. The default value is 0.: This means to create a new table and write the result to row number 1. If a value is specified for row which lies beyond the length of the table, the table is extended up to that row.

Examples:

WRITE/RADEC_TABLE source  RA=12,20,30  DEC=20,10,40
WRITE/RADEC_TABLE source  40.20        -10.50        2
WRITE/RADEC_TABLE coord   40.20        -10,30        2
