LOW REST API
- GET /subarrays
Returns the array configurations available
- Status Codes:
200 OK – Successful response with the list of array configurations.
- GET /continuum/calculate
Calculate the sensitivity of an SKA LOW observation in continuum for the input parameters.
- Query Parameters:
num_stations (number) – The number of LOW antenna stations
duration (number) – The duration of the observation in hours
pointing_centre (string) – Pointing centre in HH:MM:SS[.ss] DD:MM:SS[.ss]
freq_centre (number) – Central frequency in MHz
bandwidth_mhz (number) – Bandwidth for the continuum observation in MHz
- Status Codes:
200 OK – Successful response with the results of the sensitivity calculation.
400 Bad Request – Request parameters failed validation, either against the OpenAPI spec or the domain specific validation,eg the spectral window not lying within the allowed range.
- GET /{spectral_mode}/weighting
Compute the weighting correction factor to apply for an SKA LOW continuum observation
- Parameters:
spectral_mode (string) – Calculator spectral mode
- Query Parameters:
weighting_mode (string) – Weighting strategy used (Required)
robustness (number) – Robust parameter. Only required and considered if the weighting is set to robust.
subarray_configuration (string) – SKA LOW subarray configuration (Required)
pointing_centre (string) – Pointing centre in HH:MM:SS[.ss] DD:MM:SS[.ss] (Required)
freq_centre (number) – Central frequency in MHz (Required)
- Status Codes:
200 OK – Result of an image weighting calculation
400 Bad Request – Request parameters failed validation, either against the OpenAPI spec or the domain specific validation,eg the spectral window not lying within the allowed range.
5XX – An error occurred making the calculation
- GET /zoom/calculate
Calculate the sensitivity of an SKA LOW observation in zoom mode for the input parameters.
- Query Parameters:
num_stations (number) – The number of LOW antenna stations
duration (number) – The duration of the observation in hours
pointing_centre (string) – Pointing centre in HH:MM:SS[.ss] DD:MM:SS[.ss]
freq_centre (number) – Central frequency in MHz
spectral_resolution_hz (number) – Spectral resolution/channel width of the zoom window. The channel width of the narrowest zoom window is given by (781250 * 32/27)/(4096 * 16) = 14.129 Hz (rounded to 3 d.p.).
total_bandwidth_khz (number) – The total bandwidth of the zoom window in kHz. Smallest allowed value is the channel width given above multiplied by 1728 channels (~24.4 kHz). Maximum allowed value is 3125 kHz.
- Status Codes:
200 OK – Successful response with the results of the sensitivity calculation.
400 Bad Request – Request parameters failed validation, either against the OpenAPI spec or the domain specific validation,eg the spectral window not lying within the allowed range.
