######################################################################## # # NASA/IPAC EXTRAGALACTIC DATABASE # Batch Job Request Help File for Search by Parameters # Form date: 9 March 2005 # # This is a detailed description of the input data format for NED's # Batch Search-by-Parameters functions. # # >>>>> Please send us your comments. <<<<< # ######################################################################## # # General comments # # There is another batch form that you may use for data searches # constrained by object name or reference code. The present form # should be used for searches constrained by various parameters # (equatorial or Galactic coordinates, redshift, object type, or # name prefix). # # The abbreviated template batch request forms can be filled in by you # and submitted by e-mail to the NED batch processor. Those forms # are shorter than these fully-commented forms, though these longer # forms are also accepted by the batch processor. # # If you retype any of the UPPER_CASE commands listed in the template # request form, be aware that they must be correctly reproduced in # their upper case format. If these commands are not in UPPER_CASE # letters, the batch processor will reject your request. # # Blank lines and lines beginning with the `#' symbol are ignored. # # Please make sure that your files contain only flat (7-bit) ASCII # characters, i.e. no special control characters. In particular, # line-feed/carriage-return characters from MS-DOS and MS-Windows # formatted files will confuse the batch processor. # # Please also note that batch request files must have lines shorter # than 72 characters, and that they may NOT have email "attachments" # of any kind. # # Any given batch request file may contain several types of searches, # but the present processor supports a MAXIMUM OF 3000 REQUESTS PER # INPUT FILE. A single request (e.g. for all B3 radio sources) may # give an output of many thousands of objects, however. # # If a request yields more than 10,000 objects, NED will send you a # message asking you to resubmit the job in smaller batches. # # To formulate a request, edit the Batch Job Template For Search by # Parameters Request Form by either accepting or changing the # suggested defaults, and by supplying the information needed for # the individual searches. # # Once your request file is filled in, e-mail it to # # >>>>>>>> nedbatch@ipac.caltech.edu <<<<<<<< # # Batch jobs are normally run every fifteen minutes. Thus, you may # usually retrieve your results via FTP within half an hour of # submitting your job. During times of heavy usage, large batch jobs # may take longer to run. In any case, NED will send you a notice via # email when your job has run and is ready to be retrieved. ######################################################################## # # There are three distinct sections that you will need to fill in. # # 1) OUTPUT FILE NAME, FORMAT, and COMPRESSION SCHEME. # # a) OUTPUT_FILENAME # # Here you need to specify a filename into which the search # results will be written by the NED batch processor. This file # will be written on our local machine, and you may retrieve it # via FTP. # # The filename may be any reasonable number of characters in # length. If it duplicates a filename already in use, the batch # processor will add a suffix to it. If you don't specify a # filename, the processor will assign one for you. The return # e-mail message will tell you the file name and file size. # # b) OUTPUT_OPTION # # NED has three output formats: `standard', `compact', or # `compact_2'. The standard form is longer with more information # on each object. The two compact forms include only some # essential information for each object. The default is standard, # but either of the compact forms may give you the information # you need. We suggest you try short jobs with different output # formats to see which one will suit your needs. # # c) COMPRESS_OPTION # # If you wish to compress your output file, NED can use two # compression formats: UNIX `compress' or GNU `gzip'. The # respective output files will have a suffix `.Z' or `.gz' # appended. You will need to use the UNIX `uncompress' command to # uncompress `.Z' files, or the GNU `gunzip' command to uncompress # `.gz' files. If you do not want to compress your output, choose # the default option `none'. # # 2) ENVIRONMENT PARAMETERS. # # These are Global Flags, adopted by default or specified by you, # which remain unchanged during processing of a single batch job. # # 3) REQUESTS. # # Using this form, you may only set up a search by parameters: # Equatorial and/or Galactic coordinates, heliocentric redshift, # object type, or name prefix. # # The other NED batch form allows the following searches: # # a) Find objects by their name: FIND_OBJECTS_BY_NAME # b) Find objects near a name: FIND_OBJECTS_NEAR_NAME # c) Find objects near a position: FIND_OBJECTS_NEAR_POSITION # d) Find objects by IAU-style name: FIND_OBJECTS_BY_IAU_NAME # e) Find objects by reference code: FIND_OBJECTS_BY_REFCODE # f) Find details for a refcode: FIND_REFCODE_DETAIL # g) Find references for an object: FIND_REFERENCES # h) Find photometry for an object: FIND_PHOTOMETRIC_DATA # i) Find position data for an object: FIND_POSITION_DATA # j) Find redshift data for an object: FIND_REDSHIFT_DATA ######################################################################## # # DETAILED INSTRUCTIONS # # Here is an example batch job form with notes on filling it out. # ######################################################################## # # SET OUTPUT FILE NAME, FORMAT AND COMPRESSION SCHEME # # Replace the x's on the next line with an OUTPUT FILENAME of your # choosing.

Use either `DEC_between' OR # `DEC_not_between', not both. You may use any of the coordinate # formats (e.g. decimal degrees, sexagesimal notation) recognized by # NED. If you use sexagesimal notation, we recommend specifying the # units explicitly, as in # # 00h00m00.0s and +00d00m00s # or # 00h00.0m and +00d00m # and so forth. # # In this example, a search is set up to return nearby radio # sources, infrared sources, and QSOs in the Virgo Cluster area.

For another # search, copy the entire `Search by Parameters' section above, add # it to the form just after the END_OF_DATA line, and replace the # parameters with others as needed. ######################################################################## END_OF_REQUESTS # END_OF_REQUESTS signals the end of all data input in this batch # session.
