## Step by Step Introduction:
##1) Input
##1) Input Data
Input to sagecal must be in CASA MS format, make sure to create a column in the MS to write output data as well. The data can be in raw or averaged form, also initial calibration using other software can be also applied.

###2b)Cluster file format:
cluster_id chunk_size source1 source2 ...
e.g.
'''
```
0 1 P0C1 P0C2
2 3 P11C2 P11C1 P13C1
'''
```
Note: putting -ve values for cluster_id will not subtract them from data.
chunk_size: find hybrid solutions during one solve run. Eg. if -t 120 is used
to select 120 timeslots, cluster 0 will find a solution using the full 120 timeslots while cluster 2 will solve for every 120/3=40 timeslots.
