11 A: No. Which ancillary file is used when processing a measurement is defined in the 11 A: No. Which ancillary file is used when processing a measurement is defined in the

53 Q: Is it possible to submit a single analog profile for processing?
54
55
56 A: It depepends on the type of product you ar trying to calculate.
57
58 * If the product is a linear polarization calibration, it is possible to submit a timeseries containing
59 one single analog profile. This is allowed because some stations are performing depolarization calibration measurements using
60 single profiles. If the errors are present they will be taken into account for the calculation of the error on calibration constant.
61 If they are not the error on calibration constant is calculate as the standard deviation withing the calibration range.
62
63 * If the product to calculate is NOT a linear polarization calibration, if the raw analog error have not been provided we need at
64 least 3 raw profile in order to compute the statistical error
