 | msin.nchan | integer | 0 | Number of channels to use from the input MS (0 means till the end). It can be an expression with `nchan` (nr of input channels) as parameter. E.g. \\ ''15*nchan/16'' |
 | msin.starttime | string | first time in MS | Center of first time slot to use; if < first time in MS, dummy time slots are inserted. A date/time must be specified in the casacore MVTime format, e.g. 19Feb2010/14:01:23.817 |
+| msin.starttimeslots | int | 0 | Starting time slot. This can be negative to insert flagged time slots before the beginning of the MS. |
 | msin.endtime | string | last time in MS | Center of last time slot to use; if > last time in MS, dummy time slots are inserted. |
 | msin.ntimes | integer | 0 | Number of time slots to use (0 means till the end). |
