36 * birdie: remove self generated birdies in 128 MHz 

37 data by deleting every other channel and the edge 

38 channels 

39 * reweight: suppress ringing of interference spikes by 

40 reweighting the lag spectrum for minimum spectral sidelobe response 

41 * noxycorr: do not apply the xyphase 

42 correction using the noise cal xy phase measurements (use if you 

43 know there was a problem with the measurements) 

44 * compress: Compress the data, model, corrected data and imaging weight 

45 columns (may reduce dynamic range) 

46 * fastmosaic: Produce a MeasurementSet with small tiles to optimize I/O 

47 for observations with a large number of pointings and a short time (a few 

48 integrations) on each pointing. Failing to use this options for such data 

49 may cause very inefficient access, especially for continuum data 

50 (10-100 times slower) 

51 * hires: For data taken in binning mode: set the TIME_CENTROID column to 

52 the center of each bin (normally center of integration interval). The TIME column is 

53 unaffected. TIME_CENTROID will no longer be in time order for dual frequency 

54 mode.
