C 43 39 Type
C
C 44-45 40 Stream
C
C 46-49 41 Expver
C
C 50-51 42 Forecast number or singular vector number. Zero for
C analysis.
C
C
C If type = 60 (perturbed analysis):
C
C 52-93 43-57 Set to zero.
C
C
C For other types, the area definition (octets 58 to 77) should always be
C coded. Other octets from 53 to 93 may be coded as zeroes.
C
C Allowed ranges are [-90,90] for latitudes and [0,360] for longitudes.
C
C
C 52-53 43 Number of iterations.
C
C 54-55 44 Number of singular vectors computed.
C
C 56 45 Norm used at initial time.
C
C 57 46 Norm used at final time.
C
C 58-61 47 Multiplication factor to convert latitude/longitude
C and accuracy from real to integer.
C
C 62-65 48 Latitude in degrees of north-west corner of forecast
C verification area multiplied by KSEC1(47).
C
C 66-69 49 Longitude in degrees of north-west corner of forecast
C verification area multiplied by KSEC1(47).
C
C 70-73 50 Latitude in degrees of south-east corner of forecast
C verification area multiplied by KSEC1(47).
C
C 74-77 51 Longitude in degrees of south-east corner of forecast
C verification area multiplied by KSEC1(47).
C
C 78-81 52 Accuracy multiplied by KSEC1(47).
C
C 82-83 53 Number of singular vectors evolved.
C
C 84-91 54-55 Ritz numbers.
C Given ritz, then:
C KSEC1(54) = NINT( LOG10(RITZ)-5 )
C KSEC1(55) = NINT( RITZ/ EXP(LOG(10.0)*KSEC1(54) ) )
C Thus:
C RITZ = KSEC1(55)*EXP( LOG(10.0)*KSEC1(54) )
C
C 92 56 For all types, this is the period in hours between
C the time when the targeted observations are taken
C (the reference time in KSEC1(10:14)) and the forecast
C verification time.
C For singular vectors, this is the optimisation time.
C
C 93 57 Forecast lead time (hours)
C For all types, this is the lead time of forecast(s)
C on which sensitive area prediction is based. The lead
C time is the time from the initialization of the
C forecast to the reference time in KSEC1(10:14).
C
C 94 58 WMO identifier of the centre from which the data
C originated
C
C 95-96 59 Method number
C
C 97-98 60 Total number of forecasts in ensemble (or zero if
C not appropriate).
C
C 99 61 Shape of verification region:
C 0: lat-lon box as given by KSEC1(48-51)
C 1: circular region with centre at
C latitude = 0.5*(KSEC1(48)+KSEC1(50))/KSEC1(47) (deg)
C longitude = 0.5*(KSEC1(49)+KSEC1(51))/KSEC1(47) (deg)
C and with
C radius = 0.5*(KSEC1(48)-KSEC1(50))/(KSEC1(47)*111.199)
C = great-circle distance in km
C
C This is the largest circle fitting in a lat-lon box
C defined by KSEC1(48-51).
C
C 100 Reserved. Set to zero.
