The following page describes the basic IPAC Table Format, which can be used with IRSA Services that support multi-object searches. http://irsa.ipac.caltech.edu/applications/DDGEN/Doc/ipac_tbl.html Please pay particular attention to the "DBMS Cons...
Depending on the nature of the constraints, you could be looking at downloading a very large number of objects. To prevent a single user's very large query from impacting our performance for other users, IRSA's catalog search tool will fail for queries...
In the "Search Catalog" pane, click on the "Set Column Restrictions" link in the lower left. At the top of the dialog box that pops up, select the "Long Form" menu item. Then click "OK" and "Search".
You cannot input a list of object names directly into the Catalog Search Tool. However, you can feed your list (with no header) into the IPAC Table Reformat and Validation Service: http://irsa.ipac.caltech.edu/applications/TblCheck/ [1] If you cl...

This usually means that the table you uploaded is in a binary file format, such as .doc, .rtf or .xls. In order for a table to be read by IRSA's services, it must be in a plain text ASCII file. If you are using Microsoft Word, be aware documents may ap...
This error indicates that the table you uploaded contains too many data columns and too few column names. If you are using IPAC ASCII Column-Aligned, or tab- or comma-delimited formats, the number of cells containing data must not exceed the number of ...
This error message means that the column names in your table do not sufficiently describe an object name, or the locations on the sky using ra, dec, glon, glat, etc. Clean up the column names so they are recognizable by IRSA services. See Supported ...
Three common conditions may result in this error message. REASON #1: When using IPAC Table Format, data are located beneath the vertical bars in the header. SOLUTION: Align the data with the columns in the header. (See IPAC Table Format [1]) R...
REASON: The table is using IPAC ASCII Column-Aligned format, and the columns are misaligned. SOLUTION: Make sure the table data are contained within the boundaries set by the vertical lines in the column header rows.
The GLIMPSE Catalogs null any sources that are bright enough to be in danger of nonlinear detector response. The GLIMPSE Archives list the best fluxes that can be measured from such sources despite the nonlinearity. Note that the Vizier version of t...
This error indicates that you have not entered a search radius. Please try again with a valid search radius.
In IPAC Table Format, column names can be the combination of characters, numbers, or underscores ("_"). Blanks, white spaces, tabs, dashes ("-"), or any other special characters are not allowed as part of column names. In this case, the parentheses mus...
Your table probably contains a column with data type "int", but with values that have more digits than allowed by this data type. Try changing "int" to "long".
Here are some tips for making your large catalog search return faster: 1. If you suspect that your query might return results larger than 2 Gb, you will need to break it up into smaller queries. It can be difficult to predict the size of the returne...
The IRSA GLIMPSE holdings include Catalogs and Archives. The Catalog is a MORE RELIABLE list of sources, and the Archive is a MORE COMPLETE list both in number of sources and flux measurements at each wavelength (less nulling of fluxes). Vizier has concat...
To retain only the most robust flux densities, apply the following cuts: 1. Make a SNR cut. Each source has 5 columns ending in "FluxType", four for each of the IRAC channels and one for MIPS-24. Flux densities directly detected in an image with SNR...
