Imaging Parameters

Which imaging parameters do you want returned from your query?

Note: "Target Imaging" refers to the imaging data (run) and/or processing (rerun) combination used in selecting targets for spectroscopic followup; "Best Imaging" refers to the "latest and greatest" run/rerun combination and therefore generally supersedes the run/rerun combination of "Target Imaging".

Caveat: In rare instances the "Best Imaging" object matched to a spectrum may NOT correspond to the original "Target Imaging" object. For example, this may occur when there were deblending problems in the "Target Imaging", such as when a bright off-center HII region was targeted instead of the parent galaxy, and where that HII region is then properly treated in the "Best Imaging" and is no longer a cataloged object. When in doubt, please compare the magnitudes and coordinates of the "Target Imaging" and "Best Imaging" objects.

Useful imaging parameter combinations:

The SDSSname parameter returns the official IAU SDSS designation for the object, in the format:

Getting FITS files from the SAS (Science Archive Server)

After you press Submit, the page that displays the results of the query will include the appropriate button(s) to upload the results of the query to the SAS to retrieve the corresponding raw FITS file data. If you only request imaging data and include the columns run, rerun, camcol, and field (these are included in the minimal and typical column lists), then the Upload list of fields to SAS button will be displayed on the results page (below the query results table). If you request spectroscopic data, and include the columns plate, mjd and fiberid in the output (included in the minimal and typical column lists), then the Upload list of spectra to SAS button will be displayed on the results page so you can retrieve FITS files for the spectra.

Position Constraints

Which positional constraints (if any) do you want applied to your query?

Rectangular Search

Valid formats (J2000):

• raMin/raMax in decimal degrees (D.ddddd) or in sexagesimal hours, minutes, seconds (HH:MM:SS.ss or HH MM SS.ss)
• decMin/decMax in decimal degrees (+/-DD.ddddd) or in sexagesimal degrees, arcminutes, arcseconds (+/-DD:MM:SS.s or +/-DD MM SS.s)

Cone Search

For a given RA and DEC, the cone search returns all objects within the search radius that meet your search constraints.

Valid formats (J2000):

• raCenter in decimal degrees (D.ddddd) or in sexagesimal hours, minutes, seconds (HH:MM:SS.ss or HH MM SS.ss)
• decCenter in decimal degrees (+/-DD.ddddd) or in sexagesimal degrees, arcminutes, arcseconds (+/-DD:MM:SS.s or +/-DD MM SS.s)
• radius in decimal arcminutes (M.mmm)

Do you want to search the proximities for a list of ra's and dec's?

Proximity Search allows you to enter a list of RA/Dec positions and find objects near those positions. For each RA and Dec you enter, the proximity search returns objects within the specified search radius that meet your search constraints.

The list can be either entered directly into the box or uploaded as a file. In either case, the positions must be of the form:

ra dec [sep]

with each item separated by a comma or space. The first two numbers, "ra" and "dec," are requried - these are the sky positions (J2000) around which to search. The third, "sep," is optional - it is the separation distance or seach radius, in arcminutes, around which to search. If you do not enter a value for "sep," the default is 1 arcminute.

Valid formats for positions are:

• ra in decimal degrees (D.ddddd); or in sexagesimal hours, minutes, seconds (HH:MM:SS.ss or HH MM SS.ss)
• dec in decimal degrees (+/-DD.ddddd); or in sexagesimal degrees, arcminutes, arcseconds (+/-DD:MM:SS.s or +/-DD MM SS.s)
• sep in decimal arcminutes (S.ssss...)

"Nearest Only" returns only one match for each position you enter - the sky object meeting your search criteria that is nearest to the position you entered.

"All Nearby" returns all objects meeting your criteria within your search radius.

That means that "Nearest Only" only will return at most one match for each position you entered; "All Nearby" could return many matches for each position.

Spectroscopy Constraints

Which spectroscopic constraints (if any) do you want applied to your query?

Redshift

Do you want to search over a given range in redshift?

Redshifts less than zero are possible (e.g., for stars), as are redshifts greater than 5 (some QSOs, but also objects with poorly measured redshifts). The "Redshift warning flags" toggle allows you to remove the constraint that there should be no redshift warnings (default). Uncheck this if you want to allow spectra that have redshifts with warnings associated with them. The warning flags are encoded as bits in the zWarning column in the SpecObjAll table.

Spectral Classification

What type of objects (as automatically classified by their spectra) do you want returned from your query?

The options are:

Primtarget

Which type of objects do you want returned from your query? (Here, the object type is from the spectroscopic target selection algorithms, where the objects have been classified photometrically or by matchup with other catalogs.) (primary target categories)

The primTarget field is a bit mask specifying which primary target categories the object was selected in. If you select one or more bits in the At least one of these bits ON menu, then the bit-wise OR of each of those bits is computed and it must be greater than 0. If you select one or more of the bits in the All of these bits OFF menu, then the bit-wise AND of all those bits is computed and it must be equal to 0.

The bits are defined as:

Sectarget

Which type of objects do you want returned from your query? (Here, the object type is from the spectroscopic target selection algorithms, where the objects have been classified photometrically or by matchup with other catalogs.) (secondary target categories)

The secTarget field is a bit mask specifying which primary target categories the object was selected in. If you select one or more bits in the At least one of these bits ON menu, then the bit-wise OR of each of those bits is computed and it must be greater than 0. If you select one or more of the bits in the All of these bits OFF menu, then the bit-wise AND of all those bits is computed and it must be equal to 0.

The bits are defined as:

BossTarget

The bits are defined as:

EbossTarget

The bits are defined as:

Imaging Constraints

Which imaging constraints (if any) do you want applied to your query?

Sky Version

Magnitude Type

1. Petrosian magnitudes and colors,
2. PSF magnitudes and colors, or
3. model magnitudes and colors.

Magnitudes

Do you want to search over given range in u, g, r, i, and/or z magnitudes?

Colors

Do you want to search over given range in u-g, g-r, r-i, and/or i-z colors?

Object Type

Which type of objects do you want returned from your query? (Here, the object type is the classification from the photometric pipeline, and are based upon how well an object matches a stellar, de Vaucouleurs, or exponential profile.)

The object types are:

• Extended Sources (e.g., galaxies)
• Point Sources (e.g., stars, QSOs)
• Sky Fibers (sky)
• Unknown (?)

Photometric Quality

You can restrict the search to objects that have minimum photometric quality as determined by the score column in the PhotoObjAll table. The possible values of score are 0 and 1 (0=BAD, 1=ACCEPTABLE). Independently of this constraint, you may also opt to return the score value from the PhotoObjAll table for each object in your search, by checking the "Return value" checkbox. If no value is entered in the "Match Score" box, no quality constraint will be applied but the score will still be returned with your query results.

Photo Flags

Which set of object flags (from photo) do wish to query on?

These flags are discussed in more detail in the document "Understanding the SDSS Image Data Processing Flags".

Photo flags can be set (ON) or (OFF). If you select one or more flags in the At least one of these flags ON menu, then the bit-wise OR of each of those flag bits is computed and it must be greater than 0. If you select one or more of the flags in the All of these flags OFF menu, then the bit-wise AND of all those flag bits is computed and it must be equal to 0.

The object photo flags are:
