SEED pole position errors not supported Response file ************* A response file is built from a number of stages listed as above. At the moment there is no response record, but there may be in the future. Stage is a sparse record since only the fields needed are used. The field usage changes in some fields according to the NMX stage type 0 thru 8. The mapping from NMX to SEED is as above. Each stage consists of (nominally) 32 lines (0..31) Line[0] must start with ( and is for comment Additional lines following line 0 and starting with ( are also comment lines[1..30] are normal items (see example table) line[31] holds the first coefficient During reading this file, all characters on each line between newline and colon are ignored. A conversion error results if the actual type does not match the expected type. The exception is the line with coefficients. The first coefficient is on line 31, thereafter, numbers are read until the numerator and denominator coefficient counts are satisfied, with all the numerator coefficients first. Coefficients are separated by space, newline, comma or tab. Numbers are characters from the set 0..9+-.Ee. There can be one or more coefficients on line 31, or for example, each coefficient could be separated from the next by newline. After the last coefficient, the next line is expected to be the comment line starting with ( of the next stage. Notes on each field in NMX Stage record *************************************** ulRespKey Response filename should be anystring..res szDescription Typically type of overall response. Only needed in stage[0]. rtmStartDate; rtmEndDate; Start and end date of response. If both equal, the end date is infinity, meaning the response is current. rtmLoadDate; pszDBComment Ignored, but may be used in the future usNumStages Read from stage[0]. Used to check that expect number of stages are present. usStageNum Stage number. Some utilities may ignore this, so it is important to list stages in chronological order anyways. ulStageKey Assigned by MakeSEED usSeedBlockette Critical parameter. Tells MakeSEED kind of blockette to make. szName (26) Description of stage, e.g. seismometer type, filter type, etc chSeedType This field is used to tell MAKESEED which type of SEED primary blockette to make from this stage. MAKESEED may also make a second or secondary blockette from the stage information. See elsewhere for details. szInputUnits (21) szOutputUnits (21) Used to build SEED Units Abbreviations Blockette 34 rNormFactor rNormFreq Used to set corresponding fields in blockette 43. Since optional, values of 1.0 are used for now. rInSamSec If rInSamSec is non-zero, causes blockette 48 to be built from this info. usDecimation usDecimationOffset Used to determine decimiation, as well as offset caused by decimation. rDelayEstimate Optional field in SEED. Not used for now. rDelayApplied Corrective delay applied to samples after filtering. This allows for non-causal filters. rGainOrSensitivity rGainFreq If rGainOrSensitivity is non-zero, causes blockette 47 to be built from this info. rFrequency Not used usType This field is used by PMResponse to set type of response. Note that this field allows several types which are not supported by SEED. szDesign (21) A place to put how (for example) the FIR coefficients were derived. Ignored. usNumTerms usDenTerms Number of each type of coefficients in coefficient field below. rtmLoadDate Ignored. Slot for date put in database. pszDBComment Ignored.
