16 delmod ---- Deletes model representations in the MS 

17 

18  

19 This utility task is to be used to delete the model visibility data 

20 representations in the MS. 

21 

22 --------- parameter descriptions --------------------------------------------- 

23 

24 vis Name of input visibility file (MS) 

25 otf Delete the on-the-fly model data keywords 

26 Default=True 

27  

28 The 'otf' representation is the 'scratch-less' 

29 model data, stored as keywords in the MS header 

30 containing model data formation instructions. It 

31 is generated by the setjy, ft, and tclean tasks 

32 (usescratch=False), and if present, overrides the 

33 MODEL_DATA column (if present). If a user wishes 

34 to use the MODEL_DATA column _after_ having 

35 operated with the 'otf' representation, this task 

36 can be used to delete the 'otf' represenatation 

37 to make the MODEL_DATA column visible. (Create 

38 the MODEL_DATA column by using usescratch=True in 

39 setjy, ft, or clean; or by running the clearcal 

40 task with addmodel=True.) 

41 field Select field using field id(s) or field name(s) 

42 Subparameter of otf 

43 Default: '' (all fields' models will be deleted) 

44 scr Delete the MODEL_DATA scr col (if it exists) 

45 Default: False 

46  

47 Note: it is not possible to delete the MODEL_DATA 

48 column per field. 

49  

50 If otf=F and scr=F, delmod will provide a listing 

51 of the header field records. 

52 RETURNS void
