cheta.utils.get_telem_table#

cheta.utils.get_telem_table(msids, start, stop, time_pad=15 * u.min, unit_system='eng')#

Fetch telemetry for a list of MSIDs and return as an Astropy Table.

This interpolates all the MSIDs to the time base of the first MSID in the list. It also fetches time_pad more than requested to ensure that the samples are complete (e.g. if the interval is between MSID samples).

If no telemetry is available for the requested interval then an empty table is returned with all float columns.

Parameters:

  • msids – fetch msids list

  • start – start time for telemetry (CxoTime-like)

  • stop – stop time for telemetry (CxoTime-like)

  • time_pad – Quantity time pad on each end for fetch (default=15 min)

  • unit_system – unit system for fetch (“eng” | “cxc” | “sci”, default=”eng”)

Returns:

Table of requested telemetry values from fetch
