Search VO collections, the Hubble Source Catalog, and create DOIs for data you publish |
It is possible to search MAST for multiple targets at once, by first uploading list of target names and coordinates. On this page... |
Here are he steps for uploading a list of targets to the Portal:
Introduction | Notes | ||
---|---|---|---|
1 | Prepare a list of targets on your local machine, following the formatting rules below. This minimal example file (right) uses a list of names and coordinates of 4 Galactic globular clusters.
| globulars.txt | |
2 | Click the Upload Target List button. | ||
3 | Enter the location of your target list in the upload dialog box, and click "Upload" | ||
4 | Select one or more of your targets in the results table. | ||
5 | Click the cross-match button. | ||
6 | Select a MAST collection against which to cross-match the coordinates of you targets. Also select a search radius about the targets. Then click the Cross Match button. |
It is possible to perform other actions with user tables beyond cross-matching with an uploaded table, such as creating new table columns or plots of column values. |
Uploading a large list of targets, and then cross-matching against a large catalog such as All Observations, may take a long time to execute, and may return an unwieldy list of matches. |
The Upload tool can import custom tables in two file formats: VOTABLE and CSV. See the description of VOTable file format. A CSV-formatted table should be prepared with the following in mind:
#
. An exception to this is that before the header line you may specify a column datatype line with #@
, then a comma-separated list of types.int
, float
, string
, ra
and dec
, with the latter two being interpreted from either decimal or sexagesimal coordinates. If no datatypes are specified, the software will attempt to determine them.RA
or RAJ2000
.DEC
or DECJ2000
.s_region
or regionSTCS
.
