16 getcalmodvla ---- Retrieve calibrator brightness distributions from a VLA web service. 

17 

18  

19 This application retrieves calibrator information via a VLA web service 

20 and writes this information as a componentlist so that it may be used by applications 

21 downstream. 

22  

23 

24 --------- parameter descriptions --------------------------------------------- 

25 

26 outfile The name of the output component list to be written. Must be specified 

27 Default: none, must be specified 

28 Example: outfile="3c273.cl" 

29 overwrite Overwrite a file or directory of the same name of outfile if it exists. If overwrite=False and a file or directory of the same name as outfile exists, an exception will be thrown. 

30 source The calibrator name. The case-insensitive names 

31 "3C48", "3C286", "3C138", 

32 and "3C147" are supported. Exactly one of source 

33 or direction must be specified. 

34 direction An alternative to source. It is the direction of the calibrator. The supported 

35 formats are of the form "EPOCH LONGITUDE LATITUDE", eg 

36  

37 "J2000 12:34:56 -12.34.56". 

38 "J2000 19h53m50 40d06m00" 

39 "B1950 292.5deg -40.0deg" 

40 "ICRS 13:05:27.2780 -049.28.04.458" 

41 "GALACTIC 47.5rad -60.22rad" 

42  

43 Only astronomical coordinate systems should be used; eg AZEL is right out. The web service 

44 will attempt to locate a known calibrator near this direction, where "near" is defined by 

45 the web service team. Exactly one of source or direction must be specified. 

46 band A string representing the case-insensitive code of 

47 the band for which the data are required. For the VLA, 

48 supported codes are "P", "L", "S", "C", "X", "U", "K", "A", and "Q". 

49 obsdate The date for which to obtain the calibrator information. If numeric, 

50 is assumed to be an MJD. If a string, is assumed to be a date and must 

51 be of the form "YYYY-MM-DD". 

52 refdate The reference date after which new database entries will be ignored. If numeric, 

53 is assumed to be an MJD. If a string, is assumed to be a date and must 

54 be of the form "YYYY-MM-DD". Used to support 

55 historical reproducibility. A non-positive value will result in this parameter being ignored, 

56 and the most recent entry will be used (which may be later than obsdate). 

57 hosts List of hostnames to use when querying the web service. They will be queried in 

58 order until a successful response is received.
