16 listsdm ---- Lists observation information present in an SDM directory. 

17 

18 Given an SDM directory, this task will print observation information to the logger and return a dictionary keyed by scan. 

19 

20 --------- parameter descriptions --------------------------------------------- 

21 

22 sdm Name of input SDM directory 

23 RETURNS void

29 The listsdm task reads SDM XML tables, processes the 

30 observation information contained therein, and prints this 

31 information to the CASA log. It will also return a dictionary 

32 keyed on scan number. The dictionary contains the following 

33 information: 

34  

35 'baseband' list of baseband name(s) 

36 'chanwidth' list of channel widths (Hz) 

37 'end' observation end time (UTC) 

38 'field' field ID 

39 'intent' scan intent(s) 

40 'nchan' list of number of channels 

41 'nsubs' number of subscans 

42 'reffreq' list of reference frequencies (Hz) 

43 'source' source name 

44 'spws' list of spectral windows 

45 'start' observation start time (UTC) 

46 'timerange' start time - end time range (UTC) 

47  

48 Example: 

49  

50 myscans = listsdm(sdm='AS1039_sb1382796_2_000.55368.51883247685') 

51  

52 Prints information about the requested SDM to the CASA logger 

53 and returns a dictionary with scan information in 'myscans'. 

54  

55 Keyword argument: 

56  

57 sdm -- Name of input SDM directory. 

58 example: sdm='AG836_sb1377811_1.55345.300883159725'
