This MR is the following part of !376 (merged)
The goal is to create the necessary comparison stars list, under the form of a .csv file (NINA-style).
It can be used in two ways:
- CLI style
1 - open a sequence and plate solve the current image
2 - select the variable star with the command catsearch (allows Siril to get basic data such as Vmag and Bmag of the V star). (This was the goal of the previous MR).
3 - get the list of stars from the APASS catalogue with the command starsget
4 - sort the stars (command starssort) by magnitude and BV (2 criterias) to match the target magnitude and B-V as close as possible while keeping a 5-10 stars
5 - check the result (command starswrite) in the console
- GUI style
1 - open a sequence and plate solve the current image
2 - select the variable star with Search (ctrl+alt+/)
3 - in the Plot tab, a new button appeared. Clicking will automatically get the stars from the APASS catalogue, sort them with predefined parameters and display the result. This is the lazy method. The result can (must) be refined with the previous commands.
After that, a .csv file will by created, ready to be used in the "NINA Exoplanet" process.
As a result (and for illustration only, as the max number of ref stars has been intentionally released), here is the view after Light curve process,
with -N(arrow) option:
and with -W(ide) option:
and a light curve (of a poor session) with use of the générated csv file :
The csv file including additional information is in the form:
#Sorted comparison stars for HD 189733 from APASS according to custom criterias
#delta_Vmag= 4.00, delta_BV = 0.40
