10
-
11
- - `rso.csv` - object information
12
- - `data/` - directory containing tracks measurements in `.parquet` files
13
- - `bulk_idx.txt` - contains the index of last bulk file downloaded from the MMT database
14
-
15
- ## Object information
16
-
17
- - `mmt_id` - Identification number of the object in MMT database.
18
- - `norad_id` - Norad identification number of the object.
19
- - `name` - Name of the object.
20
- - `country` - Country of origin.
21
- - `variability` - Variability: "non-variable", "aperiodic", "periodic".
22

-
25
- Parquet files are structured with the following fields:
26
-
27
- - `id` - Identification number of the record.
28
- - `norad_id` - Norad identification number of the object.
29
- - `period` - Apparent rotational period in seconds.
30
- - `timestamp` - Start of the observation timestamp in the format '%Y-%m-%d %H:%M:%S'
31
- - `name` - Name of the object.
32
- - `variability` - Variability: 0 (nonvariable), 1 (aperiodic), 2 (periodic).
33
- - `time` - A list of observation times.
