### Query Help

The tooltips that appear when you hover over the search boxes will give examples of searches, and show the unit in which to enter numerical quantities. The name resolver (SESAME) will resolve names of non-solar system objects using the SIMBAD, NED, and Vizier databases.

By default, the results of a search will be a list of publically available, raw observations of science targets. To see a project-level view, and/or prorietary data, choose the appropriate options in the lower-right box. In order to see also data from calibrator observations, select the appropriate entries from the "Scan Intent" field.

Below are a list of operators and wildcards that may be used in the search fields (apart from the name resolver field, which accepts no operators).

Numerical Operators | String Operators | String Wildcards | Logical Operators
--- | --- | --- | ---
Equal = | Equal ~ | Any text * | Or |
Not Equal != | Exactly equal (case sensitive) = | Any single character ? |
Less than < | Exactly equal (no wild cards) == |  |
Less than or equal ≤ | Not equal !~ |  |
Greater than > | Not exactly equal (no wildcards) != |  |
Greater than or equal ≥ |  |  |
Range .. |  |  |

Position Source name (Resolver)
Source name (Resolver) |  |  |
Source name (Resolver) Case-insensitive search for source name, to be resolved with Sesame. Wildcard matching is disabled. Usage. Use Sesame (via. NED, Simbad and VizieR) to parse names commonly found throughout literature. A green tick indicates a successful search, otherwise, a red cross is returned. Example Cen A NGC3375 ARP220 No tooltip information is available Source name (ALMA) Source name (ALMA) ALMA source name. Description Name of the source as registered in the ASDM. Partial matches through wildcards (?, *), and boolean OR expressions ("|"), can be used. Example GRB021004 "R Scl" RA Dec RA Dec Right Ascension, Declination Description RA and Dec may be expressed in sexagesimal, with colon-separated hours:minutes:seconds degrees:minutes:seconds, or in decimal degrees. A range may also be specified using the operators listed under "Query Help". A search radius in degrees can be added to the end separated by a comma. Unit Hours:Minutes:Seconds and Degrees:Minutes:Seconds Example 12:13:14.0 -00:01:02.1 12:13:14.0 -00:01:02.1, 20 181.0192 -0.01928 181.0192 -0.01928, 30 181..185 >-0.1928 >12:13:14.0 0..40 | Energy Frequency Frequency Reference sky frequency. Description Observed (tuned) reference frequency on the sky. Unit GHz Example >100 <300 100 .. 300 !(100 .. 300) 100 .. 300 | 600 .. 900 Bandwidth Bandwidth Total bandwidth. Description Total Bandwidth Unit GHz Example 1.2 .. 2.5 >2.5 <1.2 <1.2 | >4.0 Spectral resolution Spectral resolution Estimated frequency resolution (in kHz). Description Estimated frequency resolution from all the spectral windows, using median values of channel widths. Unit kHz Example <70 >1e6 2e6 .. 3e6 Band Band ALMA receiver band. Description ALMA receiver band. | Time Observation date Observation date Field integration start timestamp. Description Start time of the first integration on the field. Example >01-01-2011 <31-12-2011 01-01-2011 .. 01-02-2011 Integration time Integration time Total field integration time. Description Aggregated integration time for the field in the ASDM. Unit s Example >12.5 <30 30 .. 60 !(1 .. 300) | Polarisation Polarisation type Polarisation type Polarisation products. Description Polarisation products provided.
Observation Water vapour Water vapour Estimated precipitable water vapour (in mm). Description Estimated precipitable water vapour from the XML_CALWVR_ENTITIES table. Unit mm Example !null <0.5|null < 0.49 | >55.5 | Project Project code Project code Project code. Description Project code, in the form YYYY.NNNNN.C.AAA, where: Example 2010.2.00010.N 2010.* 2010.?.*.CSV *.CSV !(*.CSV | *.SIM) Project title Project Title ALMA Project Title Description Case-insensitive search over the project title Example *GALAXY* *?ebula* PI name PI Full Name ALMA PI name Description case-insensitive partial match over the full PI name. Wildcards can be used Example Smith, Fred SMI* fr?d |  | Options View: raw data project Results View Select if the results should be displayed per observation or per project. Description Per default the search results are displayed so that one row of the results table corresponds to one observation in the raw data. If you are only interested in a list of projects that match the search criteria, select here the project option. public data only Data type Per default only publicly available data is shown. If you also want to see proprietary data, uncheck this checkbox. Description ALMA data is protected by a proprietary period of usually 12 months. Per default only those data that have gone out of their proprietary period are shown in the Results Table. If you are a PI and are looking for your own data, if the PI has delegated the access of their data to you, if you want to see which data has been observed or if you want to see which data is becoming public when, please uncheck this checkbox. science observations only Observation type Per default only science sources are shown. If you also want to see the calibration sources, uncheck this checkbox. Description Scan intent list for the observed field.

### Results Help

Query results appear on this page. If the "raw" view was selected, there is one entry per observation of each source. This means that for a given project several rows are typically displayed for the same source, as are individual mosaic pointings. The "project" view will contain one row per project data delivery.

Columns in the results table may be sorted by clicking on the column header cell and filtered by entering a filter value in the box below each column heading. The "More columns" link at the top-right of the results table allows the display of further metadata columns. Select the rows you are interested in and click the "Submit download request" button. This will identify the data deliveries that contain the selected data and offer them for download through the ALMA Request Handler.

Below are a list of operators that may be used in the filter boxes.

Numerical Operators | String Operators | String Wildcards | Logical Operators
--- | --- | --- | ---
Equal (Default) | Equal (Default) | Any text * | Or |
Not Equal ! |  |  |
Less than < |  |  |
Less than or equal ≤ |  |  |
Greater than > |  |  |
