use Soandso\ContinentalIndex\Register;

$report = new Register($inputType, $source, $inputTempUnits, $outputTempUnits, $latitude);

$inputType - Supported types of source data:
Register::FILE
Register::ARRAY
Register::JSON

$source - Input source:
1. File (Show file path)
Source data structure:
Year, space, temperature amplitude value
Example:
2022 78.5

2. array:
[
  Year, temperature amplitude value
]
Example:
[
  [2017, 80.9],
  [2018, 70.3],
  ............
]

3. json:
This format is an array (see above) encoded into a json string

$inputTempUnits - Input temperature amplitude units:
Register::FAHRENHEIT
Register::CELSIUS

$outputTempUnits - Output temperature amplitude units:
Register::FAHRENHEIT
Register::CELSIUS

$latitude - Location latitude

$index->getIndex(string $title, string $format, string $filePath = null);

$title - Type index of continentality
The following methods for calculating the continentality index are supported:

1. Hromov continentality index - Register::HROMOV_INDEX
2. Gorchinsky continentality index - Register::GORCHINSKY_INDEX
3. Conrad continentality index - Register::CONRAD_INDEX
4. Zenker continentality index - Register::ZENKER_INDEX


$format - Output format
Register::FILE
Register::ARRAY
Register::JSON

$filePath - The path to the directory for extracting the results file
