top source SpdfGetDataCallback

result = SpdfGetDataCallback(statusInfo, progressInfo, callbackData)

Return value

Parameters

statusInfo in type=strarr

progressInfo in type=lon64arr

callbackData in type=reference

top source SpdfGetData

result = SpdfGetData(dataset, variables, timeSpans [, binInterval=double] [, binInterpolateMissingValues=byte] [, binSigmaMultiplier=int] [, binOverrideDefaultBinning=byte] [, dataview=string] [, endpoint=string] [, /keepfiles] [, /quiet] [, /verbose] [, callback_function=string] [, callback_data=reference] [, sslVerifyPeer=int])

Return value

Parameters

dataset in type=string

name of dataset to get data from.

variables in out type=strarr

On entry, names of variables whose values are to be gotten. If the first (only) name is "ALL-VARIABLES", then the resulting CDF will contain all variables. On exit, names of variables actually read (may be more than requested).

timeSpans in type=strarr(n, 2)

ISO 8601 format strings of the start and stop times of the data to get.

Keywords

binInterval in optional type=double default=60.0D

binning interval (seconds).

binInterpolateMissingValues in optional type=byte default=1

flag indicating whether to interpolate missing values.

binSigmaMultiplier in optional type=int default=0

standard deviation multiplier used for rejecting data.

binOverrideDefaultBinning in optional type=byte default=0

flag indicating whether to override the default selection of variables to bin. 0 = use default selection (only variables with the ALLOW_BIN attribute set). 1 = bin additional variables beyond just those with the ALLOW_BIN attribute set.

dataview in optional type=string default='sp_phys'

name of dataview containing the dataset.

endpoint in optional type=string default='https://cdaweb.gsfc.nasa.gov/WS/cdasr/1'

URL of CDAS web service.

keepfiles in optional type=boolean default=false

The KEEPFILES keyword causes SpdfGetData to retain the downloaded data files. Normally these files are deleted after the data is read into the IDL environment.

quiet in optional type=boolean default=false

SpdfGetData normally prints an error message if no data is found. If QUIET is set, no error messages is printed.

verbose in optional type=boolean default=false

The VERBOSE keyword causes SpdfGetData to print additional status, debugging, and usage information.

callback_function in optional type=string

this keyword value is the name of the IDL function that is to be called during this retrieval operation. The callbacks provide feedback to the user about the ongoing operation, as well as provide a method to cancel an ongoing operation. If this keyword is not set, no callback to the caller is made. For information on creating a callback function, see "Using Callbacks with the IDLnetURL Object" in the IDL documentation.

callback_data in optional type=reference

this keyword value contains data that is passed to the caller when a callback is made. The data contained in this variable is defined and set by the caller. The variable is passed, unmodified, directly to the caller as a parameter in the callback function. If this keyword is not set, the corresponding callback parameter's value is undefined.

sslVerifyPeer in optional type=int default=spdfGetDefaultSslVerify()

Specifies whether the authenticity of the peer's SSL certificate should be verified. When 0, the connection succeeds regardless of what the peer SSL certificate contains.

Examples

     d = spdfgetdata('AC_H2_MFI', ['Magnitude', 'BGSEc'], $
           ['2013-01-01T00:00:00.000Z', '2013-01-03T00:00:00.000Z'], $
           /VERBOSE)

     The Epoch values are returned in d.epoch.dat
     The Magnitude values are in d.magnitude.dat
     The BGSEc values are in d.bgsec.dat
