I’m writing my first scientific paper as a PhD student and it’s a comparison of 6 different instruments that measure precipitation. The instruments differ massively in terms of cost, and their performance is inherently tied to that. The discussion seems pointless without giving the reader this knowledge. Simply saying “low cost” or “relatively high cost” doesn’t quite cut it for me.
I realise I’m entering risky territory, but how might I quote the price of these instruments in the paper? The separate companies do not actively publish this information, you must request a quote. Am I breaking the law or simply pissing off these companies if I attempt to publish this data?
