Execution block ID to associate scan configs to an observation. This ID is used for associating generated data, especially data products, for a given observation. Multiple scans can be linked to one observation and this ID is used as metadata to associate the data products from all scans of the same observation. This ID does not have to be unique for a scan configuration but should be unique for different observations. For example, all the data and weights files will have an EB_ID header value populated with the value supplied in this field. |

Center frequency for the Band-of-Interest. Required if Band is 5a or 5b; not specified for other Bands (not configurable for Band 1 and 2). Input for Band 5a and 5b consists of two 2.5 GHz streams; the center frequency can be independently tuned for each stream. The following nomenclature is used to refer to Band 5a and 5b streams: 5a1, 5a2, 5b1, 5b2. |

Optionally, an offset can be specified so that the entire observed band is shifted (to accommodate a Zoom Window that crosses a ‘natural’ Frequency Slice boundary). If specified, applies for all the receptors in the sub-array. Bands 1 and 2: input from the receptor consists of a single data stream; the Frequency Band Offset (FBO) should be specified for Stream 1 only. Bands 5a and 5b: input from the receptor consists of two data streams; the FBO can be specified for each stream independently. Note: For Band 5a and 5b the frequency shift is performed by the receptor (DISH). Note: This is optional and does not need to be implemented in PI3, but would be great for demo; if Team Buttons is looking for opportunities to showcase interesting GUIs, Zoom Windows are perfect opportunity (would require TMC and CSP to support these two parameters, corrBandwidth values > 0 and zoom window tuning.) |

Optionally a subset of receptors to be correlated can be specified. If not specified, all receptors that belong to the subarray are cross-correlated (i.e. visibilities for all the baselines in the subarray are generated and transmitted to SDP). Valid receptor IDs include: SKA dishes: “SKAnnn”, where nnn is a zero padded integer in the range of 001 to 133. MeerKAT dishes: “MKTnnn”, where nnn is a zero padded integer in the range of 000 to 063. |

Bandwidth to be correlated calculated as FSBW/2n, where n is in range [0..6]. When n=0 the full Frequency Slice bandwidth is correlated. BW > 0 implies ‘Zoom Window’ configuration; the spectral Zoom Window tuning must be specified. |

The Zoom Window tuning provided in absolute terms as RF center frequency. Based on that, CSP_Mid calculates tuning within the data stream received from the receptor. Must be selected so that the entire Zoom Window is within the Frequency Slice. If partially out of the FS a warning is generated. If completely outside of the FS an exception is generated. Step size <= 0.01MHz. The Frequency Band Offset can be used to shift the entire observed band in order to accommodate a Zoom Window that spans across a Frequency Slice boundary. |

Table of up to 20 x 2 integers. Each of entries contains:
Explanation: Each FSP produces 14880 (TBC) fine channels across the correlated bandwidth (Frequency Slice or Zoom Window). Channels are evenly spaced in frequency. TM shall provide the table that for each FSP and each group of 744 channels (there are 20 groups per FSP) indicates the channel averaging factor. More precisely, for each group the TMC provided table specifies:
and so on. If no entry is present for an FSP, the averaging settings of the previous FSP are still applicable. |
