Here is an initial version of the Hessi Observing Summary structure
Obs_summary = A structure containing the observing summary for one file
Obs_summary contains sub-structures:
- obs_summary.info = A structure containing the information for the
observing summary for the file
- obs_summary.accumulated_data = An array of structures containing the
accumulated data for each time interval
- obs_summary.data_gaps = An array of data gaps
- obs_summary.info tags:
- .file_id = a string identifying the file from which the
obs_summary was generated
- .file_start_time = the file start time, in a structure TBD
- .file_end_time = the file end time, in a structure TBD
- .n_time_intv = the number of time intervals, for this file
- .time_intv_duration = the nominal duration, in seconds,
of a single time interval
- .n_front_bands= the number of energy bands for the front
detector count rates
- .n_rear_bands= the number of energy bands for the rear
detector count rates
- .front_energy_bins = the energy bin edges for the front detector
fltarr(2, n_front_bands)
- .rear_energy_bins = the energy bin edges for the rear detector
fltarr(2, n_rear_bands)
- .nflags = the number of data flags
- .flag_ids = string identifiers for each data flag, e.g.,
'Attenuator State', 'SAA passage', etc.
- obs_summary.accumulated_data tags:
- .file_id = an identifier for the file from which the data was taken
- .st_time = the start time of the interval, in a structure TBD
- .sc_latitude = Latitude of the spacecraft orbit
- .sc_longitude = Longitude of the spacecraft orbit
- .sc_height = Height of the spacecraft orbit
- .front_rate = count rate of front detectors, summed over the detectors,
in n_front_bands energy bands, COUNTS/SECOND,
compressed into an an intarr(n_front_bands)
- .rear_rate = count rate of rear detectors, summed over the detectors,
in n_rear_bands energy bands, COUNTS/SECOND,
compressed into an an intarr(n_rear_bands)
- .particle_rate = count rate for particle detector, COUNTS/SECOND,
an integer.
- .front_modulation_variance = a bytarr(n_front_bands), that measures
the variance in the count rate for
front detectors
- .rear_modulation_variance = a bytarr(n_rear_bands), that measures
the variance in the count rate for
rear detectors
- obs_summary.data_gaps tags:
- st_time = data gap start time, structure TBD
- en_time = data_gap end time, structure TBD
