For a list of all services and tables belonging to this service's resource, see Information on resource 'A Database of Circumstellar OH Masers'
You can access this service using:
6.52238e-06 6.89063e-06 eV
This service is published as follows:
local means it is listed on our front page, ivo_managed means it has a record in the VO registry.
Other services provided on the underlying data include:
The following fields are available to provide input to the service (with some renderers, some of these fields may be unavailable):
| Name | Table Head | Description | Unit | UCD |

| frequency | Freq | Observed frequency | MHz | em.freq |
| hscs_pos | Position/Name | Coordinates (as h m s, d m s or decimal degrees), or SIMBAD-resolvable object | N/A | N/A |
| hscs_sr | Search radius | Search radius in arcminutes | N/A | N/A |
| maxrec | Match limit | Maximum number of records returned. Pass 0 to retrieve service parameters. | N/A | N/A |

| source_no | Source id | Unique, artificial source identifier | N/A | meta.code |
| SR | Search Radius | Search radius | deg | N/A |
| verb | Verbosity | Exhaustiveness of column selection. VERB=1 only returns the most important columns, VERB=2 selects the columns deemed useful to the average user, VERB=3 returns a table with all available columns. | N/A | N/A |
The following fields are contained in the output by default. More fields may be available for selection; these would be given below in the VOTable output fields.

| t_res | Time res. | Approximate time resolution of obs_date_* | yr | time.resolution |
The following fields are available in VOTable output. The verbosity level is a number intended to represent the relative importance of the field on a scale of 1 to 30. The services take a VERB argument. A field is included in the output if their verbosity level is less or equal VERB*10.
