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