From 12689e3d858d66e5e00e8d99f9326ef91cc0a384 Mon Sep 17 00:00:00 2001 From: Kristian Evers Date: Thu, 14 Feb 2019 14:51:39 +0100 Subject: deformation: Replace +t_obs with +dt The +t_obs parameter was confusing for users since it effectively overwrote the observation time in input coordinates. To make it more clear what is the operation is doing, users are now required to directly specify the time span for which they wish to apply a given deformation. The parameter +dt has been added for that purpose. The new parameter is mutually exclusive with +t_epoch. +dt is used when deformation for a set amount of time is needed and +t_epoch is used (in conjunction with the observation time of the input coordinate) when deformation from a specific epoch to the observation time is needed. --- src/strerrno.cpp | 1 + 1 file changed, 1 insertion(+) (limited to 'src/strerrno.cpp') diff --git a/src/strerrno.cpp b/src/strerrno.cpp index 13e9c757..01097a42 100644 --- a/src/strerrno.cpp +++ b/src/strerrno.cpp @@ -68,6 +68,7 @@ pj_err_list[] = { "only one +init allowed for non-pipeline operations", /* -57 */ "argument not numerical or out of range", /* -58 */ "inconsistent unit type between input and output", /* -59 */ + "arguments are mutually exclusive", /* -60 */ /* When adding error messages, remember to update ID defines in projects.h, and transient_error array in pj_transform */ -- cgit v1.2.3
