16 getephemtable ---- Query the JPL-Horizons database for ephemeris data and create a CASA table
19 This task retrieves the ephemeris data of a specific ephemeris object by sending
20 a query to JPL's Horizons system and creates the ephemeris data stored in a CASA table
21 format.
23 --------- parameter descriptions ---------------------------------------------
25 objectname Name of ephemeris object. The common name of major bodies such as
26 planets known in CASA will be converted into the (NAIF/SPK) ID. If the parameter, asis
27 is set to True, objectname is passed to the query as is to the JPL-Horizons system.
28 If the object ID is used asis must be set to True.
30 Default: ''
32 Example:
33 objectname='Titan'
34 objectname='606' (should set asis=True in this case)
35 asis A toggle for objectname check to be done or not before sending a query to the JPL-Horizons system.
36 Default: False
38 As described in objectname parameter description, when asis=False, objectname is checked
39 against the known objects (a list of the supported ephemeris sources in setjy task plus
40 a few others) in CASA (See the getephemtable Description section in CASA Docs).
41 Setting asis=True will skip this check/conversion thus objectname has to be uniquly
42 recognized by the JPL-Horzions system.
43 For example, objectname='Jupiter' with asis=True results in the JPL-Horizons system
44 to return no ephemeris data as multiple objects matches with the name.
45 timerange Time range of ephemeris data to be queried.
46 Default: ''
48 Standard CASA timerange specification('T0~T1'),YY/MM/DD/hh:mm,
49 or by Modified Julian date or Julian date if the string is prefixed by 'MJD' or 'JD'.
51 Example:
52 timerange = '2023/09/01/20:45~2023/09/02/04:00'
53 (Note: Both start and end times need to be fully specified starting with YYYY
54 but hours or minutes can be omitted as long as the
55 start and stop times are distinguishable. The omitted hours or minutes are translated as '00')
56 timerange = 'MJD 60175.1~60176.1'
57 interval Interval or step size of ephemeris data
58 Default: '5m'
60 A string with integer value and unit (minutes, hours, days) or
61 a string with integer value without unit (to produce equal time interval defined by
62 timerange/interval).
63 The unit can be given as the first few characters, e.g. 'm', 'min', 'h', or 'd'.
65 Note: The JPL-Horizons query allows the step size by calendar months or years however
66 the task will not convert such data to the CASA table as Measures requires the ephemeris
67 table data in equal time interval. When the calendar months or years is specified
68 for interval, the task execution will result in a SEVERE error. The raw query results
69 will be saved even such a case if rawdatafile parameter is specified.
71 Example:
73 interval='5min'
74 interval='5minutes'
75 interval='1h'
76 interval='1d'
77 outfile Output CASA table name
78 Default: ''
80 Example:
81 outfile = 'Titan_MJD60175.1-60176.1.tab'
82 rawdatafile Name of raw ephemeris data file before converting into a CASA table (optional)
83 Default: '' = No raw ephemeris data is saved
85 Useful for debugging when errors occured and/or no output table is produced.
87 Example: rawdatafile='Titan-jplhorizons.dat'
88 overwrite If True, overwrite output files (outfile, rawdatafile), if already exist
89 Default: False
